</beans>在spring上下文的配置文件引用mybatis配置文件：
<import resource="spring-mybatis.xml" />
在maven的pom.xml增加打包的配置，保证打包可以将mapper.xml包含进来：
<resources> <resource> <directory>src/main/java</directory> <includes> <include>**/*.xml</include> </includes> </resource> <resource> <directory>src/main/resources</directory> <includes> <include>**/*</include> </includes> </resource> </resources>
mapper接口测试：
文件位置截图：
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="com.test.mybatis.dao.TestMapper"> <select id="getCount" resultType="int"> SELECT COUNT(1) FROM t1 </select> </mapper>
TestMapper接口：
package com.test.mybatis.dao;
public interface TestMapper {
int getCount();
}测试代码：
package com.test.controller;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;
import com.test.mybatis.dao.TestMapper;
@RestController
@RequestMapping(value = "/test")
public class TestController {
private static final Logger logger = LoggerFactory.getLogger(TestController.class);
@Autowired TestMapper testMapper;
@RequestMapping(value= "/test", method = RequestMethod.GET)
public Object test(HttpServletRequest request, HttpServletResponse response
) {
int count = testMapper.getCount();
logger.info("test:{}", count );
return count;
}
}结果：
