快速搭建SSM框架(Maven)五步曲的方法步骤
项目完整搭建链接:https://gitee.com/DaNanHai04/ssm_parent.git
第一步 创建一个父工程:
导入父工程的pom坐标:
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
public TbBrandExample() {

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;
}

addCriterion("first_char in", values, "firstChar");
return (Criteria) this;
}
public Criteria andFirstCharNotIn(List
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() {

}
}
public static class Criterion {
private String condition;

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
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
}
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
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
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/beans/spring-beans.xsd 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">
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/beans/spring-beans.xsd
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="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">
springMVC.xml配置说明
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">
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">
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
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。
