5.框架连通测试（Spring+Mybatis）

前两篇博客已经把Spring和Mybatis基础配置完成，接下来需要测试下页面<--->服务器<--->数据库之间是否正确连通。

1. 截止目前为止，各个配置文件的内容

        <aop:advisor pointcut-ref="transactionPointcut" advice-ref="transactionAdvice" />
    </aop:config>
</beans>

2.新建测试部分
①数据库新建test表格并初始化数据：

-- ----------------------------
-- Table structure for test
-- ----------------------------
DROP TABLE IF EXISTS `test`;
CREATE TABLE `test` (
  `pagename` varchar(255) DEFAULT NULL,
  `id` int(11) NOT NULL AUTO_INCREMENT,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=2 DEFAULT CHARSET=utf8;

-- ----------------------------
-- Records of test
-- ----------------------------
INSERT INTO `test` VALUES ('testpage', '1');

②新建TestDao.java层接口和TestDaoMapper.xml

public interface TestDao {
	public String getPageAtDao();
}

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper PUBLIC "-//ibatis.apache.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.qyuz.dao.TestDao">
    <select id="getPageAtDao" resultType="string">
    	select pagename from test limit 0,1
    </select>
</mapper>

③新建ITestService.java层和TestServiceImpl.java

public interface ITestService {
	public String getPage();
}

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

import com.qyuz.dao.TestDao;
import com.qyuz.service.ITestService;

@Service
public class TestServiceImpl implements ITestService{
	
	@Autowired
	TestDao dao;

	@Override
	public String getPage() {
		// TODO Auto-generated method stub
		return dao.getPageAtDao();
	}

}

④新建TestController.java

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

import com.qyuz.service.ITestService;

@Controller
public class TestController {
	
	@Autowired
	ITestService service;

	@RequestMapping("/test")
	public String test(){
		return service.getPage();
	}

}

⑤WEB-INF/views/下新建testpage.jsp页面

<%@ page language="java" contentType="text/html; charset=UTF-8"
	pageEncoding="UTF-8"%>
<html>
<body>
<h2>测试网页，成功！</h2>
</body>
</html>

⑥最后，右击项目run as -> run on server,启动之后，在浏览器中输入http://localhost:8080/myecom/test.do 回车，显示如下：

测试成功，基础框架搭建成功！
