今日计划

按Spring+Mybatis+Maven+Mysql创建项目，并部署在云平台上，进行单元测试

今日完成

思路是本地项目完成后打包jar，上传到云平台

表结构

新建maven工程

包选war，以后可以springMVC连起来

User.java

package com.lin.domain;

public class User {

private Integer userId;

private String userName;

private String userPassword;

private String userEmail;

public Integer getUserId() {

return userId;

}

public void setUserId(Integer userId) {

this.userId = userId;

}

public String getUserName() {

return userName;

}

public void setUserName(String userName) {

this.userName = userName;

}

public String getUserPassword() {

return userPassword;

}

public void setUserPassword(String userPassword) {

this.userPassword = userPassword;

}

public String getUserEmail() {

return userEmail;

}

public void setUserEmail(String userEmail) {

this.userEmail = userEmail;

}

@Override

public String toString() {

return "User [userId=" + userId + ", userName=" + userName

+ ", userPassword=" + userPassword + ", userEmail=" + userEmail

+ "]";

}

}

UserDao.java

Dao接口，对应mapper文件

package com.lin.dao;

import com.lin.domain.User;

public interface UserDao {

public User selectUserById(Integer userId);

}

先写一个select

UserService.java和UserServiceImpl.java

service接口类和实现类

UserService.java

package com.lin.service;

import org.springframework.stereotype.Service;

import com.lin.domain.User;

public interface UserService {

User selectUserById(Integer userId);

}

UserServiceImpl.java

package com.lin.service;

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

import org.springframework.stereotype.Service;

import com.lin.dao.UserDao;

import com.lin.domain.User;

@Service

public class UserServiceImpl implements UserService{

@Autowired

private UserDao userDao;

public User selectUserById(Integer userId) {

return userDao.selectUserById(userId);

}

}

mapper文件

和dao文件对应

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.lin.dao.UserDao">

<!--设置domain类和数据库中表的字段一一对应，注意数据库字段和domain类中的字段名称不致，此处一定要！-->

<resultMap id="BaseResultMap" type="com.lin.domain.User">

<id column="USER_ID" property="userId" jdbcType="INTEGER" />

<result column="USER_NAME" property="userName" jdbcType="CHAR" />

<result column="USER_PASSWORD" property="userPassword" jdbcType="CHAR" />

<result column="USER_EMAIL" property="userEmail" jdbcType="CHAR" />

</resultMap>

<!-- 查询单条记录 -->

<select id="selectUserById" parameterType="int" resultMap="BaseResultMap">

SELECT * FROM t_user WHERE USER_ID = #{userId}

</select>

</mapper>

mybatis配置文件

mybatis-config.xml

<?xml version="1.0" encoding="UTF-8"?>  

<!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN"  

"http://mybatis.org/dtd/mybatis-3-config.dtd">

</configuration>

数据源配置jdbc.properties

jdbc_driverClassName=com.mysql.jdbc.Driver

jdbc_url=jdbc:mysql://localhost:3306/learning

jdbc_username=root

jdbc_password=admin

Spring配置

单元测试

测试基类

SpringTestCase.java

package com.lin.baseTest;

import org.junit.runner.RunWith;

import org.slf4j.Logger;

import org.slf4j.LoggerFactory;

import org.springframework.test.context.ContextConfiguration;

import org.springframework.test.context.junit4.AbstractJUnit4SpringContextTests;

import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

@ContextConfiguration(locations = { "classpath:application.xml" })

@RunWith(SpringJUnit4ClassRunner.class)

public abstract class SpringTestCase extends AbstractJUnit4SpringContextTests{

protected Logger logger = LoggerFactory.getLogger(getClass());

}

测试类

UserServiceTest.java

package com.lin.service;

import org.apache.log4j.Logger;

import org.junit.Test;

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

import com.lin.baseTest.SpringTestCase;

import com.lin.domain.User;

public class UserServiceTest extends SpringTestCase {

@Autowired

private UserService userService;

Logger logger = Logger.getLogger(UserServiceTest.class);

@Test

public void selectUserByIdTest(){

User user = userService.selectUserById(10);

        logger.debug("查找结果" + user);

}

}

单元测试

右键-debug as-jnuit test

输出debug日志

单元测试报错

一直查bug，卡了很长时间。没有解决

遇到问题

有时候eclipse单元测试通过，但是在本地用mvn clean install打包，测试不通过

eclipse自带输出功能可以成功得到war文件

收获

熟悉Spring+Mybatis+Maven+Mysql项目结构

配置maven 库镜像可以加快jar包加载速度

修改\maven\apache-maven-3.5.0\conf下的settings.xml 需要预先统一eclipse中maven配置读取位置

<mirrors>

    <mirror>

      <!--This sends everything else to /public -->

      <id>nexus</id>

      <mirrorOf>*</mirrorOf> 

      <url>http://maven.aliyun.com/nexus/content/groups/public/</url>

    </mirror>

    <mirror>

      <!--This is used to direct the public snapshots repo in the 

          profile below over to a different nexus group -->

      <id>nexus-public-snapshots</id>

      <mirrorOf>public-snapshots</mirrorOf> 

      <url>http://maven.aliyun.com/nexus/content/repositories/snapshots/</url>

    </mirror>

  </mirrors>

maven的pom文件在maven项目中eclipse窗口可以手动选取jar包，自动生产pom文件

明日计划

云服务器配置tomcat，上传项目war包并配置测试通过

解决本地项目单元测试不通过的问题
