Eclipse + Maven 搭建 SSH 环境

标签：

1、安装Maven，下载地址：http://mirrors.cnnic.cn/apache/maven/maven-3/3.3.9/binaries/apache-maven-3.3.9-bin.zip，下载后，解压缩到D:盘，系统变量中添加M2_HOME=D:\apache-maven-3.3.9，编辑PATH变量，在末尾添加%M2_HOME%\bin。

在%M2_HOME%下创建repo文件夹，编辑%M2_HOME%\conf\settings.xml，添加配置

<localRepository>D:/apache-maven-3.3.9/repo</localRepository>

2、打开Eclipse，选择Help - Install New Software，在Work with输入框中输入：http://mirror.bit.edu.cn/eclipse/technology/m2e/releases/，这是国内的mirror，速度稍微快点，Pending后，选择安装Maven Integration for Eclipse，一路Next，漫长的安装结束后，重启Eclipse。

3、选择Window - Preferences - Maven - Installations - add，选择Maven安装目录，保存结果。

4、File - New - Project，选择Maven Project，Next，Next，漫长的Retrieving archetypes后，Catalog选择Maven Central，Filter输入：maven-archetype-webapp，Next，Group Id输入：com.moapp，Artifact Id输入工程名：mavenSSH，点击Finish。

5、编辑pom.xml

15、JUnit测试文件

com.moapp.mavenSSH.service.TestUserManager.java

package com.moapp.mavenSSH.service;

import org.apache.log4j.Logger;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

import com.alibaba.fastjson.JSON;
import com.moapp.mavenSSH.beans.User;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {
		"classpath:spring.xml",
		"classpath:spring-hibernate.xml"
})
public class TestUserManager {
	private static final Logger LOGGER = Logger.getLogger(TestUserManager.class);
	@Autowired
	UserManager userManager;
	
	@Test
	public void save() {
		User user = new User();
		user.setUserName("fengwusan");
		user.setPassword("123456");
		user.setGender(0);
		Integer id = userManager.save(user);
		JSON.toJSONString(id);
	}
}

选择Debug-Debug as - JUnit Test，配置无误，则运行正常，不然需要自己调试了。
