1.首先可以resources文件夹下创建三个文件,spring-mybatis.xml、spring-mvc.xml、jdbc.propertis、log4j.properties,并修改web.xml内容。
- spring-mybatis.xml:整合spring与mybatis,并实现spring基本功能。
- spring-mvc.xml:配置使用spring-mvc。
- jdbc.propertis:资源文件,用来保存数据库相关信息。
- log4j.properties:配置日志文件。
spring-mybatis.xml

2.创建java下的目录结构
TestController.java
package fv.controller;
import fv.pojo.Test;
import fv.service.TestService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.stereotype.Controller;
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.ResponseBody;
/**
* 测试
*/
@Controller
@RequestMapping("/test")
public class TestController {
@Autowired
@Qualifier("testService")
private TestService testService;
@RequestMapping(value = "/get", method = RequestMethod.GET)
@ResponseBody
public Test getTestById(@RequestParam("id") String id) {
return testService.getById(Integer.parseInt(id));
}
}
TestService.java
package fv.service;
import fv.pojo.Test;
/**
* 测试服务接口
*/
public interface TestService {
Test getById(int id);
}
TestServiceImp.java
package fv.srv.imp;
import fv.dao.TestMapper;
import fv.pojo.Test;
import fv.service.TestService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
/**
* 测试服务
*/
@Service("testService")
public class TestServiceImp implements TestService {
@Autowired(required = false)
private TestMapper testMapper = null;
public Test getById(int id) {
return testMapper.selectByPrimaryKey(id);
}
}
Test.java
package fv.pojo;
/**
* 测试对象
*/
public class Test {
private Integer id;
private Integer test1;
private String test2;
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public Integer getTest1() {
return test1;
}
public void setTest1(Integer test1) {
this.test1 = test1;
}
public String getTest2() {
return test2;
}
public void setTest2(String test2) {
this.test2 = test2;
}
}
TestMapper.java
package fv.dao;
import fv.pojo.Test;
/**
* Test的Mapper
*/
public interface TestMapper {
Test selectByPrimaryKey(Integer id);
}
TestMapper.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="fv.dao.TestMapper">
<resultMap id="BaseResultMap" type="fv.pojo.Test">
<id column="id" property="id" jdbcType="INTEGER" />
<result column="test1" property="test1" jdbcType="INTEGER" />
<result column="test2" property="test2" jdbcType="VARCHAR" />
</resultMap>
<sql id = "Base_Column_List">
id, test1, test2
</sql>
<select id="selectByPrimaryKey" resultMap="BaseResultMap" parameterType="java.lang.Integer">
SELECT
<include refid="Base_Column_List" />
FROM test
WHERE id = #{id, jdbcType = INTEGER}
</select>
</mapper>
3.以上基本目录就创建成功了,然后设置一个tomcat服务器,进行输出,就会将maven中依赖的包输出,以上配置中并没有配置servlet-api.jar,需要手动依赖进本项目。
4.在数据库中插入一条数据,进行查询,返回JSON,如下图。
IDEA下创建Maven项目,并整合使用Spring、Spring MVC、Mybatis框架
