第二步创建ssm_pojo子模块（mybatis逆向这里不做赘述，直接将生成好的复制即可）

创建实体类TbBrand实体类

package com.itcode.pojo;

import java.io.Serializable;

public class TbBrand implements Serializable {

private Long id;

private String name;

private String firstChar;

//此处省略get/set方法以及toString方法

创建TbBrandExample条件类

package com.itcode.pojo;

import java.util.ArrayList;

import java.util.List;

public class TbBrandExample {

protected String orderByClause;

protected boolean distinct;

protected List oredCriteria;

public TbBrandExample() {

oredCriteria = new ArrayList();

}

public void setOrderByClause(String orderByClause) {

this.orderByClause = orderByClause;

}

public String getOrderByClause() {

return orderByClause;

}

public void setDistinct(boolean distinct) {

this.distinct = distinct;

}

public boolean isDistinct() {

return distinct;

}

public List getOredCriteria() {

return oredCriteria;

}

public void or(Criteria criteria) {

oredCriteria.add(criteria);

}

public Criteria or() {

Criteria criteria = createCriteriaInternal();

oredCriteria.add(criteria);

return criteria;

}

public Criteria createCriteria() {

Criteria criteria = createCriteriaInternal();

if (oredCriteria.size() == 0) {

oredCriteria.add(criteria);

}

return criteria;

}

protected Criteria createCriteriaInternal() {

Criteria criteria = new Criteria();

return criteria;

}

public void clear() {

oredCriteria.clear();

orderByClause = null;

distinct = false;

}

protected abstract static class GeneratedCriteria {

protected List criteria;

protected GeneratedCriteria() {

super();

criteria = new ArrayList();

}

public boolean isValid() {

return criteria.size() > 0;

}

public List getAllCriteria() {

return criteria;

}

public List getCriteria() {

return criteria;

}

protected void addCriterion(String condition) {

if (condition == null) {

throw new RuntimeException("Value for condition cannot be null");

}

criteria.add(new Criterion(condition));

}

protected void addCriterion(String condition, Object value, String property) {

if (value == null) {

throw new RuntimeException("Value for " + property + " cannot be null");

}

criteria.add(new Criterion(condition, value));

}

protected void addCriterion(String condition, Object value1, Object value2, String property) {

if (value1 == null || value2 == null) {

throw new RuntimeException("Between values for " + property + " cannot be null");

}

criteria.add(new Criterion(condition, value1, value2));

}

public Criteria andIdIsNull() {

addCriterion("id is null");

return (Criteria) this;

}

public Criteria andIdIsNotNull() {

addCriterion("id is not null");

return (Criteria) this;

}

public Criteria andIdEqualTo(Long value) {

addCriterion("id =", value, "id");

return (Criteria) this;

}

public Criteria andIdNotEqualTo(Long value) {

addCriterion("id <>", value, "id");

return (Criteria) this;

}

public Criteria andIdGreaterThan(Long value) {

addCriterion("id >", value, "id");

return (Criteria) this;

}

public Criteria andIdGreaterThanOrEqualTo(Long value) {

addCriterion("id >=", value, "id");

return (Criteria) this;

}

public Criteria andIdLessThan(Long value) {

addCriterion("id <", value, "id");

return (Criteria) this;

}

public Criteria andIdLessThanOrEqualTo(Long value) {

addCriterion("id <=", value, "id");

return (Criteria) this;

}

public Criteria andIdIn(List values) {

addCriterion("id in", values, "id");

return (Criteria) this;

}

public Criteria andIdNotIn(List values) {

addCriterion("id not in", values, "id");

return (Criteria) this;

}

public Criteria andIdBetween(Long value1, Long value2) {

addCriterion("id between", value1, value2, "id");

return (Criteria) this;

}

public Criteria andIdNotBetween(Long value1, Long value2) {

return (Criteria) this;

}

public Criteria andNameIsNull() {

addCriterion("name is null");

return (Criteria) this;

}

public Criteria andNameIsNotNull() {

addCriterion("name is not null");

return (Criteria) this;

}

public Criteria andNameEqualTo(String value) {

addCriterion("name =", value, "name");

return (Criteria) this;

}

public Criteria andNameNotEqualTo(String value) {

addCriterion("name <>", value, "name");

return (Criteria) this;

}

public Criteria andNameGreaterThan(String value) {

addCriterion("name >", value, "name");

return (Criteria) this;

}

public Criteria andNameGreaterThanOrEqualTo(String value) {

addCriterion("name >=", value, "name");

return (Criteria) this;

}

public Criteria andNameLessThan(String value) {

addCriterion("name <", value, "name");

return (Criteria) this;

}

public Criteria andNameLessThanOrEqualTo(String value) {

addCriterion("name <=", value, "name");

return (Criteria) this;

}

public Criteria andNameLike(String value) {

addCriterion("name like", value, "name");

return (Criteria) this;

}

public Criteria andNameNotLike(String value) {

addCriterion("name not like", value, "name");

return (Criteria) this;

}

public Criteria andNameIn(List values) {

addCriterion("name in", values, "name");

return (Criteria) this;

}

public Criteria andNameNotIn(List values) {

addCriterion("name not in", values, "name");

return (Criteria) this;

}

public Criteria andNameBetween(String value1, String value2) {

addCriterion("name between", value1, value2, "name");

return (Criteria) this;

}

public Criteria andNameNotBetween(String value1, String value2) {

addCriterion("name not between", value1, value2, "name");

return (Criteria) this;

}

public Criteria andFirstCharIsNull() {

addCriterion("first_char is null");

return (Criteria) this;

}

public Criteria andFirstCharIsNotNull() {

addCriterion("first_char is not null");

return (Criteria) this;

}

public Criteria andFirstCharEqualTo(String value) {

addCriterion("first_char =", value, "firstChar");

return (Criteria) this;

}

public Criteria andFirstCharNotEqualTo(String value) {

addCriterion("first_char <>", value, "firstChar");

return (Criteria) this;

}

public Criteria andFirstCharGreaterThan(String value) {

addCriterion("first_char >", value, "firstChar");

return (Criteria) this;

}

public Criteria andFirstCharGreaterThanOrEqualTo(String value) {

addCriterion("first_char >=", value, "firstChar");

return (Criteria) this;

}

public Criteria andFirstCharLessThan(String value) {

addCriterion("first_char <", value, "firstChar");

return (Criteria) this;

}

public Criteria andFirstCharLessThanOrEqualTo(String value) {

addCriterion("first_char <=", value, "firstChar");

return (Criteria) this;

}

public Criteria andFirstCharLike(String value) {

addCriterion("first_char like", value, "firstChar");

return (Criteria) this;

}

public Criteria andFirstCharNotLike(String value) {

addCriterion("first_char not like", value, "firstChar");

return (Criteria) this;

}

public Criteria andFirstCharIn(List values) {

addCriterion("first_char in", values, "firstChar");

return (Criteria) this;

}

public Criteria andFirstCharNotIn(List values) {

addCriterion("first_char not in", values, "firstChar");

return (Criteria) this;

}

public Criteria andFirstCharBetween(String value1, String value2) {

addCriterion("first_char between", value1, value2, "firstChar");

return (Criteria) this;

}

public Criteria andFirstCharNotBetween(String value1, String value2) {

addCriterion("first_char not between", value1, value2, "firstChar");

return (Criteria) this;

}

public static class Criteria extends GeneratedCriteria {

protected Criteria() {

super();

}

public static class Criterion {

private String condition;

private Object value;

private Object secondValue;

private boolean noValue;

private boolean singleValue;

private boolean betweenValue;

private boolean listValue;

private String typeHandler;

public String getCondition() {

return condition;

}

public Object getValue() {

return value;

}

public Object getSecondValue() {

return secondValue;

}

public boolean isNoValue() {

return noValue;

}

public boolean isSingleValue() {

return singleValue;

}

public boolean isBetweenValue() {

return betweenValue;

}

public boolean isListValue() {

return listValue;

}

public String getTypeHandler() {

return typeHandler;

}

protected Criterion(String condition) {

super();

this.condition = condition;

this.typeHandler = null;

this.noValue = true;

}

protected Criterion(String condition, Object value, String typeHandler) {

super();

this.condition = condition;

this.value = value;

this.typeHandler = typeHandler;

if (value instanceof List>) {

this.listValue = true;

} else {

this.singleValue = true;

}

protected Criterion(String condition, Object value) {

this(condition, value, null);

}

protected Criterion(String condition, Object value, Object secondValue, String typeHandler) {

super();

this.condition = condition;

this.value = value;

this.secondValue = secondValue;

this.typeHandler = typeHandler;

this.betweenValue = true;

}

protected Criterion(String condition, Object value, Object secondValue) {

this(condition, value, secondValue, null);

}

创建一个Result返回通知类

package com.itcode.pojo;

import java.io.Serializable;

public class Result implements Serializable {

private boolean success; //判断该变量

private String message; //返回的字符串

public Result(boolean success, String meshttp://sage) {

this.success = success;

this.message = message;

}

//此处省略get/set方法，自行补全

第三步创建ssm_dao子模块（逆向工程也可以生成）

创建TbBrandMapper接口类

package com.itcode.dao;

import com.itcode.pojo.TbBrand;

import com.itcode.pojo.TbBrandExample;

import org.apache.ibatis.annotations.Param;

import java.util.List;

import java.util.Map;

public interface TbBrandMapper {

int countByExample(TbBrandExample example);

int deleteByExample(TbBrandExample example);

int deleteByPrimaryKey(Long id);

int insert(TbBrand record);

int insertSelective(TbBrand record);

List selectByExample(TbBrandExample example);

TbBrand selectByPrimaryKey(Long id);

int updateByExampleSelective(@Param("record") TbBrand record, @Param("example") TbBrandExample example);

int updateByExample(@Param("record") TbBrand record, @Param("example") TbBrandExample example);

int updateByPrimaryKeySelective(TbBrand record);

int updateByPrimaryKey(TbBrand record);

List selectOptionList();

}

创建TbBrandMapper.xml文件

and ${criterion.condition}

and ${criterion.condition} #{criterion.value}

and ${criterion.condition} #{criterion.value} and #{criterion.secondValue}

and ${criterion.condition}

#{listItem}

and ${criterion.condition}

and ${criterion.condition} #{criterion.value}

and ${criterion.condition} #{criterion.value} and #{criterion.secondValue}

and ${criterion.condition}

#{listItem}

id, name, first_char

select

distinct

from tb_brand

order by ${orderByClause}

select

from tb_brand

where id = #{id,jdbcType=BIGINT}

delete from tb_brand

where id = #{id,jdbcType=BIGINT}

delete from tb_brand

insert into tb_brand (id, name, first_char

)

values (#{id,jdbcType=BIGINT}, #{name,jdbcType=VARCHAR}, #{firstChar,jdbcType=VARCHAR}

)

insert into tb_brand

id,

name,

first_char,

#{id,jdbcType=BIGINT},

#{name,jdbcType=VARCHAR},

#{firstChar,jdbcType=VARCHAR},

select count(*) from tb_brand

update tb_brand

id = #{record.id,jdbcType=BIGINT},

name = #{record.name,jdbcType=VARCHAR},

first_char = #{record.firstChar,jdbcType=VARCHAR},

update tb_brand

set id = #{record.id,jdbcType=BIGINT},

name = #{record.name,jdbcType=VARCHAR},

first_char = #{record.firstChar,jdbcType=VARCHAR}

update tb_brand

name = #{name,jdbcType=VARCHAR},

first_char = #{firstChar,jdbcType=VARCHAR},

where id = #{id,jdbcType=BIGINT}

update tb_brand

set name = #{name,jdbcType=VARCHAR},

first_char = #{firstChar,jdbcType=VARCHAR}

where id = #{id,jdbcType=BIGINT}

select id,name as text from tb_brand

第四步创建ssm_service子模块

创建一个service接口

package com.itcode.service;

import com.itcode.pojo.TbBrand;

import java.util.List;

public interface BrandService {

List findAll();

void insert(TbBrand brand);

}

创建一个service的实现类

package com.itcode.service.impl;

import com.itcode.dao.TbBrandMapper;

import com.itcode.pojo.TbBrand;

import com.itcode.service.BrandService;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.stereotype.Service;

import org.springframework.transaction.annotation.Transactional;

import java.util.List;

@Service

@Transactional

public class BrandServiceImpl implements BrandService {

@Autowired

private TbBrandMapper tbBrandDao;

@Override

public List findAll() {

return tbBrandDao.selectByExample(null);

}

@Override

public void insert(TbBrand brand) {

tbBrandDao.insert(brand);

}

jdbc.properties配置（在resource中配置）

jdbc.driver=com.mysql.jdbc.Driver

jdbc.url=jdbc:mysql://localhost:3306/数据库名?characterEncoding=utf-8

jdbc.username=用户名

jdbc.password=密码

applicationContext.xml配置

xmlns:xsi="http://w3.org/2001/XMLSchema-instance"

xmlns:context="http://springframework.org/schema/context"

xmlns:tx="http://springframework.org/schema/tx"

xsi:schemaLocation="http://springframework.org/schema/beans

http://springframework.org/schema/context

http://springframework.org/schema/context/spring-context.xsd

http://springframework.org/schema/tx

http://springframework.org/schema/tx/spring-tx.xsd">

第五步创建一个ssm_web子模块

web.xml配置

xmlns="http://java.sun.com/xml/ns/javaee"

xsi:schemaLocation="http://java.sun.com/xml/ns/javaee

http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"

version="2.5">

xmlns:xsi="http://w3.org/2001/XMLSchema-instance"

xmlns:context="http://springframework.org/schema/context"

xmlns:mvc="http://springframework.org/schema/mvc"

xsi:schemaLocation="http://springframework.org/schema/beans http://springframework.org/schema/beans/spring-beans.xsd http://springframework.org/schema/context http://springframework.org/schema/context/spring-context.xsd http://springframework.org/schema/mvc http://springframework.org/schema/mvc/spring-mvc.xsd">

WriteMapNullValue

WriteDateUseDateFormat

xmlns:xsi="http://w3.org/2001/XMLSchema-instance"

xmlns:context="http://springframework.org/schema/context"

xmlns:mvc="http://springframework.org/schema/mvc"

WriteMapNullValue

WriteDateUseDateFormat

创建一个BrandController类

package com.itcode.controller;

import com.itcode.pojo.Result;

import com.itcode.pojo.TbBrand;

import com.itcode.service.BrandService;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.web.bind.annotation.RequestBody;

import org.springframework.web.bind.annotation.RequestMapping;

import org.springframework.web.bind.annotation.RestController;

import java.util.List;

@RestController

@RequestMapping("/brand")

public class BrandController {

@Autowired

private BrandService brandService;

@RequestMapping("/findAll")

public List findAll(){

return brandService.findAll();

}

@RequestMapping("/insert")

public Result insert(@RequestBody TbBrand brand){

try {

brandService.insert(brand);

return new Result(true, "新增成功");

} catch (Exception e) {

e.printStackTrace();

return new Result(false, "新增失败");

}

最后配置一下tomcat，启动tomcat可以了，如果想要测试我们的接口可以使用Postman进行测试。
