Spring2.5.6开发环境搭建图文教程

Spring2.5.6开发环境搭建的过程,供大家参考,具体内容如下
1、jar 包准备:
spring 2.5.6 的 jar 包(链接: https://pan.baidu.com/s/1geHM6D9 密码: himj),如图:
commons-logging-1.2(链接: 下载地址),如图:
JUnit 4.7(链接: 下载地址),如图:
2、建立 User Library
2.1 建立 spring 2.5.6 的 User Library
2.1.1 通过路径 Window --> Preferences --> Java --> Build Path --> User Libraries
2.1.2 创建步骤,如下列的图:
这样 spring 2.5.6 Library 就创建好了,以后如果有新的jar包要加进来,可以选中library、点击 Add External JARs进行添加,想加多少加多少。
2.2 建立 JUnit4 的 User Library
2.2.1 通过路径 Window --> Preferences --> Java --> Build Path --> User Libraries
2.2.2 创建步骤,如下列的图:
进入添加User Library 的界面后
建好的两个 Library 如上图。
3、创建相关的一些类和接口,本测试程序创建了 User、UserDAO、UserDAOImpl、UserService,代码如下:
User
package com.bjsxt.model;
public class User {
private String username;
private String password;
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
}
UserDAO
package com.bjsxt.dao;
import com.bjsxt.model.User;
public interface UserDAO {
public void save(User u);
}
UserDAOImpl
package com.bjsxt.dao.impl;
import com.bjsxt.dao.UserDAO;
import com.bjsxt.model.User;
public class UserDAOImpl implements UserDAO{
public void save(User u) {
System.out.println("a user saved!");
}
}
UserService
package com.bjsxt.service;
import com.bjsxt.dao.UserDAO;
import com.bjsxt.model.User;
public class UserService {
private UserDAO userDAO;
public void addUser(User u){
this.userDAO.save(u);
}
public UserDAO getUserDAO() {
return userDAO;
}
public void setUserDAO(UserDAO userDAO) {
this.userDAO = userDAO;
}
}
4、编写与上面类对应的配置文件 beans.xml(名字随便取)
beans.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">
<bean id="u" class="com.bjsxt.dao.impl.UserDAOImpl"></bean>
<bean id="userService" class="com.bjsxt.service.UserService">
<property name="userDAO">
<ref bean="u"/>
</property>
</bean>
</beans>
5、编写 spring 测试类:
UserServiceTest
package com.bjsxt.service;
import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import com.bjsxt.model.User;
public class UserServiceTest {
@Test
public void testAddUser() throws Exception {
ApplicationContext ctx = new ClassPathXmlApplicationContext("beans.xml");//初始化ApplicationContext对象,加载配置文件beans.xml
UserService service = (UserService)ctx.getBean("userService");//从容器中取
User u = new User();
u.setUsername("zhangsan");
u.setPassword("zhangsan");
service.addUser(u);//容器中已经配置了UserDAOImpl了,并把DAOImpl注入到service之中,所以service直接就可以保存了
}
}
结果:
