Spring Boot整合mybatis(一)实例代码

sprig-boot是一个微服务架构,加快了spring工程快速开发,以及简便了配置。接下来开始spring-boot与mybatis的整合。

1、创建一个maven工程命名为spring-boot-entity,pom.xml文件配置如下:

xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

4.0.0

com.spring.boot.entity

spring-boot-entity

jar

0.0.1-SNAPSHOT

releases

Nexus Release Repository

http://localhost:8081/nexus/content/repositories/releases/

snapshots

Nexus Snapshot Repository

http://localhost:8081/nexus/content/repositories/snapshots/

xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

4.0.0

com.spring.boot.entity

spring-boot-entity

jar

0.0.1-SNAPSHOT

releases

Nexus Release Repository

http://localhost:8081/nexus/content/repositories/releases/

snapshots

Nexus Snapshot Repository

http://localhost:8081/nexus/content/repositories/snapshots/

然后创建一个包,命名为com.spring.boot.entity,在该包下创建一个User.java文件,内容如下:

/**

* Copyright (c) Windliven 2016 All Rights Reserved

*

* @author liyj

* @date 2017年7月11日 下午2:34:32

* @since V1.0.0

*/

package com.spring.boot.entity;

/**

* TODO

*

* @author liyj

* @date 2017年7月11日 下午2:34:32

*

*/

public class UserEntity {

/**

* id

*/

private String id;

/**

* name

*/

private String name;

/**

* pass

*/

private String pass;

/**

* email

*/

private String email;

/**

* iphone

*/

private String iphone;

public UserEntity() {}

public UserEntity(String id) {this.id = id;}

public String getId() {

return id;

}

public void setId(String id) {

this.id = id;

}

public String getName() {

return name;

}

public void setName(String name) {

this.name = name;

}

public String getPass() {

return pass;

}

public void setPass(String pass) {

this.pass = pass;

}

public String getEmail() {

return email;

}

public void setEmail(String email) {

this.email = email;

}

public String getIphone() {

return iphone;

}

public void setIphone(String iphone) {

this.iphone = iphone;

}

}

到此,spring-boot-entity工程创建完成。

2、创建一个maven工程,命名为spring-boot-interface,pom.xml文件配置如下:

xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

4.0.0

com.spring.boot.inter

spring-boot-interface

0.0.1-SNAPSHOT

com.spring.boot.entity

spring-boot-entity

0.0.1-SNAPSHOT

releases

Nexus Release Repository

http://localhost:8081/nexus/content/repositories/releases/

snapshots

Nexus Snapshot Repository

http://localhost:8081/nexus/content/repositories/snapshots/

xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

4.0.0

com.spring.boot.inter

spring-boot-interface

0.0.1-SNAPSHOT

com.spring.boot.entity

spring-boot-entity

0.0.1-SNAPSHOT

releases

Nexus Release Repository

http://localhost:8081/nexus/content/repositories/releases/

snapshots

Nexus Snapshot Repository

http://localhost:8081/nexus/content/repositories/snapshots/

然后创建一个包,命名为com.spring.boot.inter.service,在该包下创建UserService.java接口类。内容如下:

/**

* Copyright (c) Windliven 2016 All Rights Reserved

*

* @author liyj

* @date 2017年7月11日 下午2:31:20

* @since V1.0.0

*/

package com.spring.boot.inter.service;

import java.util.List;

import com.spring.boot.entity.UserEntity;

/**

* TODO

*

* @author liyj

* @date 2017年7月11日 下午2:31:20

*

*/

public interface UserService {

/*

* insert

*/

void insert(UserEntity entity);

/*

* deleteEntity

*/

void deleteEntity(UserEntity entity);

/*

* deleteById

*/

void deleteById(String id);

/*

* updateEntity

*/

void updateEntity(UserEntity entity);

/*

* updateById

*/

void updateById(String id);

/*

* getOne

*/

UserEntity getOne(String id);

/*

* getList

*/

List getList();

}

到此,spring-boot-interface工程完成。

3、创建一个maven工程,命名为spring-boot-main,pom.xml文件内容如下:

xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

snapshots

Nexus Snapshot Repository

http://localhost:8081/nexus/content/repositories/snapshots/

然后创建包,命名为com.spring.boot.base,在该包下创建DataBaseConfig.java文件,文件内容如下:

/**

* Copyright (c) Windliven 2016 All Rights Reserved

*

* @author liyj

* @date 2017年7月12日 上午9:53:09

* @since V1.0.0

*/

package com.spring.boot.base;

import javax.sql.DataSource;

import org.apache.ibatis.session.SqlSessionFactory;

import org.mybatis.spring.SqlSessionFactoryBean;

import org.mybatis.spring.mapper.MapperScannerConfigurer;

import org.slf4j.Logger;

import org.slf4j.LoggerFactory;

import org.springframework.context.annotation.Bean;

import org.springframework.context.annotation.Configuration;

import org.springframework.context.annotation.Primary;

import org.springframework.core.io.support.PathMatchingResourcePatternResolver;

import org.springframework.jdbc.datasource.DataSourceTransactionManager;

import org.springframework.transaction.PlatformTransactionManager;

import org.springframework.transaction.annotation.EnableTransactionManagement;

import com.mchange.v2.c3p0.ComboPooledDataSource;

/**

* TODO

*

* @author liyj

* @date 2017年7月12日 上午9:53:09

*

*/

@Configuration

@EnableTransactionManagement

public class DataBaseConfig {

private final Logger log = LoggerFactory.getLogger(DataBaseConfig.class);

@Bean

@Primary

public DataSource getDataSource() throws Exception {

log.debug("config dataSource");

ComboPooledDataSource cpds = new ComboPooledDataSource();

cpds.setDriverClass("com.mysql.jdbc.Driver");

cpds.setJdbcUrl("jdbc:mysql://localhost:3306/springboot");

cpds.setUser("root");

cpds.setPassword("root");

return cpds;

}

@Bean

public PlatformTransactionManager getTransactionManager() throws Exception {

return new DataSourceTransactionManager(getDataSource());

}

@Bean

public SqlSessionFactory getSqlSessionFactory() throws Exception {

SqlSessionFactoryBean sfb = new SqlSessionFactoryBean();

sfb.setDataSource(getDataSource());

sfb.setTypeAliasesPackage("com.spring.boot.entity");

PathMatchingResourcePatternResolver resolver = new PathMatchingResourcePatternResolver();

sfb.setMapperLocations(resolver

.getResources("classpath:/mapper/*.xml"));

return sfb.getObject();

}

@Bean

public MapperScannerConfigurer getMapperScannerConfigurer() {

MapperScannerConfigurer msc = new MapperScannerConfigurer();

msc.setBasePackage("com.mybloc.personal.mapper");

msc.setSqlSessionFactoryBeanName("sqlSessionFactory");

return msc;

}

}

创建一个包,命名为com.spring.boot.dao,在该包下创建UserMapper.java文件,该文件是一个接口类,内容如下:

/**

* Copyright (c) Windliven 2016 All Rights Reserved

*

* @author liyj

* @date 2017年7月11日 下午6:24:35

* @since V1.0.0

*/

package com.spring.boot.dao;

import java.util.List;

import com.spring.boot.entity.UserEntity;

/**

* TODO

*

* @author liyj

* @date 2017年7月11日 下午6:24:35

*

*/

public interface UserMapper {

public void insertOne(UserEntity entity);

public void delete(UserEntity entity);

public void update(UserEntity entity);

public UserEntity getOne(UserEntity entity);

public List getList();

}

在src/main/resources目录下创建一个mapper文件目录,在该目录下创建UserMapper.xml文件,内容如下:

insert into user(id,name,pass,email,iphone)

values(#{id},#{name},#{pass},#{email},#{iphone})

delete from user where id = #{id}

update user set email = #{email},iphone = #{iphone} where id = #{id}

select id,

name,

pass,

email,

iphone

from user

where id = #{id}

select id,

name,

pass,

email,

iphone

from user

接下来创建包,命名为:com.spring.boot.service,在该包下创建UserServiceImpl.java文件,内容如下:

/**

* Copyright (c) Windliven 2016 All Rights Reserved

*

* @author liyj

* @date 2017年7月11日 下午4:18:55

* @since V1.0.0

*/

package com.spring.boot.service;

import java.util.List;

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

import org.springframework.stereotype.Service;

import org.springframework.transaction.annotation.Transactional;

import com.spring.boot.dao.UserMapper;

import com.spring.boot.entity.UserEntity;

import com.spring.boot.inter.service.UserService;

/**

* TODO

*

* @author liyj

* @date 2017年7月11日 下午4:18:55

*

*/

@Transactional(readOnly=false)

@Service

public class UserServiceImpl implements UserService {

@Autowired

private UserMapper userMapper;

/*

* @see com.spring.boot.inter.service.UserService#insert(com.spring.boot.entity.UserEntity)

*/

public void insert(UserEntity entity) {

userMapper.insertOne(entity);

System.out.println("insert");

}

/*

* @see com.spring.boot.inter.service.UserService#deleteEntity(com.spring.boot.entity.UserEntity)

*/

public void deleteEntity(UserEntity entity) {

userMapper.delete(entity);

System.out.println("deleteEntity");

}

/*

* @see com.spring.boot.inter.service.UserService#deleteById(java.lang.String)

*/

public void deleteById(String id) {

userMapper.delete(new UserEntity(id));

System.out.println("deleteById");

}

/*

* @see com.spring.boot.inter.service.UserService#updateEntity(com.spring.boot.entity.UserEntity)

*/

public void updateEntity(UserEntity entity) {

userMapper.update(entity);

System.out.println("updateEntity");

}

/*

* @see com.spring.boot.inter.service.UserService#updateById(java.lang.String)

*/

public void updateById(String id) {

userMapper.update(new UserEntity(id));

System.out.println("updateById");

}

/*

* @see com.spring.boot.inter.service.UserService#getOne(java.lang.String)

*/

@Transactional(readOnly=true)

public UserEntity getOne(String id) {

return userMapper.getOne(new UserEntity(id));

}

/*

* @see com.spring.boot.inter.service.UserService#getList()

*/

@Transactional(readOnly=true)

public List getList() {

return userMapper.getList();

}

}

再创建一个包,命名为com.spring.boot.controller,在该包下创建UserController.java文件,内容如下:

/**

* Copyright (c) Windliven 2016 All Rights Reserved

*

* @author liyj

* @date 2017年7月11日 下午6:08:00

* @since V1.0.0

*/

package com.spring.boot.controller;

import java.util.Collection;

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

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

import org.springframework.cache.Cache;

import org.springframework.cache.CacheManager;

import org.springframework.data.redis.core.RedisTemplate;

import org.springframework.data.redis.core.ValueOperations;

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

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

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

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

import com.spring.boot.entity.UserEntity;

import com.spring.boot.inter.service.UserService;

/**

* TODO

*

* @author liyj

* @date 2017年7月11日 下午6:08:00

*

*/

//@SpringBootApplication(scanBasePackages = {"com.spring.boot"})

@RestController

@RequestMapping("/user")

public class UserController {

@Autowired

private UserService userService;

@Autowired

private CacheManager cacheManager;

@Autowired

private RedisTemplate redisTemplate;

@Value("${testName}")

private String name;

@Value("${testPass}")

private String pass;

@RequestMapping(value = "/say", method = RequestMethod.GET)

public String sayHello() {

return "hello spring boot";

}

@RequestMapping(value = "/insert", method = RequestMethod.GET)

public String insert() {

UserEntity userEntity = new UserEntity();

userEntity.setId("111");

userEntity.setName("liyj");

userEntity.setPass("123456");

userEntity.setEmail("704603154@qq.com");

userEntity.setIphone("18211140412");

userService.insert(userEntity);

return "success";

}

@RequestMapping(value = "/one/get", method = RequestMethod.GET)

public UserEntity getOne(@RequestParam String id) {

return userService.getOne(id);

}

}

接着创建一个包,命名为com.spring.boot.start,在该包下创建StartMain.java文件,内容如下:

/**

* Copyright (c) Windliven 2016 All Rights Reserved

*

* @author liyj

* @date 2017年7月11日 下午4:52:32

* @since V1.0.0

*/

package com.spring.boot.start;

import org.mybatis.spring.annotation.MapperScan;

import org.springframework.boot.SpringApplication;

import org.springframework.boot.autoconfigure.EnableAutoConfiguration;

import org.springframework.context.annotation.ComponentScan;

import org.springframework.context.annotation.Configuration;

/**

* TODO

*

* @author liyj

* @date 2017年7月11日 下午4:52:32

*

*/

@EnableAutoConfiguration

@ComponentScan(basePackages = "com.spring.boot")

@Configuration

@MapperScan(value={"com.spring.boot.dao"})

public class StartMain {

public static void main(String[] args) {

SpringApplication.run(StartMain.class, args);

}

}

最后测试,启动StartMain类中的main()方法,项目便启动了,可以正常的从浏览器中访问和测试。
