spring-boot-mybatis
最近闲来无事，整合了一下springBoot-Mybatis，确实比springMVC配置简单，闲话不说了，看代码
一、结构：
二、配置文件
1.pom.xml
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

spring.datasource.username=root
spring.datasource.password=1234
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
server.port=8011由于springBoot自带tomcat，默认端口8080，不便有调试，所以修改端口server.port=8011
3、userMapper.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.lyc.dao.UserMapperDao">
<select id="getAllUserInfo" resultType="com.lyc.model.User">
select name, age,password from user;
</select>
<select id="findUserInfo" resultType="com.lyc.model.User">
select name, age,password from user where age = #{couponNo};
</select>
</mapper>4.实体类user
package com.lyc.model;
public class User {
public int id;
public String name;
public int age;
public String password;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
}
5.userMapperDao
package com.lyc.dao;
import java.util.List;
import com.lyc.model.User;
public interface UserMapperDao {
//findUserInfo
public User findUserInfo(int age);
//getAllUserInfo
public List<User> getAllUserInfo();
}6.UserController.java
package com.lyc.controller;
import java.util.List;
import org.apache.log4j.Logger;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.context.request.RequestContextHolder;
import org.springframework.web.context.request.ServletRequestAttributes;
import com.lyc.dao.UserMapperDao;
import com.lyc.model.User;
@Controller
public class UserController {
private Logger logger = Logger.getLogger(UserController.class);
@Autowired
private UserMapperDao userMapperDao;
@RequestMapping("/getAllUserInfo")
@ResponseBody
public List<User> getAllUserInfo() {
List<User> user = userMapperDao.getAllUserInfo();
if(user!=null){
System.out.println("size:"+user.size());
logger.info("size:"+user.size());
}
return user;
}
@RequestMapping("/getUserInfo")
@ResponseBody
public User getUserInfo() {
int age = Integer.parseInt(((ServletRequestAttributes) RequestContextHolder.getRequestAttributes()).getRequest().getParameter("age"));
User user = userMapperDao.findUserInfo(age);
if(user!=null){
System.out.println("user.getName():"+user.getName());
logger.info("user.getAge():"+user.getAge());
}
return user;
}
}7.启动类，我命名成了demo
package com.lyc;
import org.apache.ibatis.session.SqlSessionFactory;
import org.apache.log4j.Logger;
import org.mybatis.spring.SqlSessionFactoryBean;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.core.io.support.PathMatchingResourcePatternResolver;
import org.springframework.jdbc.datasource.DataSourceTransactionManager;
import org.springframework.transaction.PlatformTransactionManager;
import javax.sql.DataSource;
@EnableAutoConfiguration
@SpringBootApplication
@ComponentScan
@MapperScan("com.lyc.dao")
public class demo {
private static Logger logger = Logger.getLogger(demo.class);
//DataSource配置
@Bean
@ConfigurationProperties(prefix="spring.datasource")
public DataSource dataSource() {
return new org.apache.tomcat.jdbc.pool.DataSource();
}
//提供SqlSeesion
@Bean
public SqlSessionFactory sqlSessionFactoryBean() throws Exception {
SqlSessionFactoryBean sqlSessionFactoryBean = new SqlSessionFactoryBean();
sqlSessionFactoryBean.setDataSource(dataSource());
PathMatchingResourcePatternResolver resolver = new PathMatchingResourcePatternResolver();
sqlSessionFactoryBean.setMapperLocations(resolver.getResources("classpath:/mapper/*.xml"));
return sqlSessionFactoryBean.getObject();
}
@Bean
public PlatformTransactionManager transactionManager() {
return new DataSourceTransactionManager(dataSource());
}
/**
* Main Start
*/
public static void main(String[] args) {
SpringApplication.run(demo.class, args);
logger.info("============= SpringBoot Start Success =============");
}
}
数据库就不写了，很简单的一个
这样我们就配置好了，让我们启动一下看效果，这里值得注意的是，我们不需要写项目名称，因为在main方法中已经内嵌了一下tomcat
---------我只是分隔一下，怕看不情况-----------
好的，完成。
如果需要源码去我的git上面下载，https://github.com/Abel-Li/Spring-boot.git
