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: ),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
1

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 } } |
