1.为web项目添加Spring
1.将spring有关联的包添加大项目中：
spring.jar
cglib.jar
jakarta-commons我文件夹下的jar （ commons-attributes-compiler.jar 删除）
log4j.jar
2.创建applicationContext.xml 文件(还没有找到该DTD 文件的位置)
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:aop="http://www.springframework.org/schema/aop"
xmlns:tx="http://www.springframework.org/schema/tx"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd
http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.0.xsd
http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.0.xsd">
</beans>
项目启动成功
3.测试spring
创建一个bean Person
在spring配置文件中配置 将 name属性注入
创建一个beanTestSpring
将person 注入到 TestSpring
写一个测试类 Servlet
public class SpringServletTest extends HttpServlet {
protected void service(HttpServletRequest arg0, HttpServletResponse resp)
throws ServletException, IOException {
// TODO Auto-generated method stub
ApplicationContext ac = new ClassPathXmlApplicationContext("applicationContext.xml");
Person p =(Person)ac.getBean("person");
p.info();
TestSpring ts = (TestSpring)ac.getBean("testSpring");
ts.test();
resp.setCharacterEncoding("UTF-8");
resp.setContentType("test/html");
PrintWriter pw = resp.getWriter();
pw.println("请切换到控制台，查看执行结果.........");
}
}
在web.xml中配置servlet测试
<servlet>
<servlet-name>testSpring</servlet-name>
<servlet-class>com.younglibin.www.lb.test.SpringServletTest</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>testSpring</servlet-name>
<url-pattern>/spring/test</url-pattern>
</servlet-mapping>
启动项目，地址栏输入：
http://localhost:8080/上下文/spring/test
可以在bean职工输出一些东西在控制台
4.在web中配置Spring
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
为了便于项目文件管理将spring配置文件放在classes目录下的spring中，在这里指定文件路径
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath*:spring/applicationContext.xml</param-value>
</context-param>
修改测试类中获得spring的方式：
package com.younglibin.www.lb.test;
import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.ServletContext;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.context.ApplicationContext;
import org.springframework.web.context.support.WebApplicationContextUtils;
import com.younglibin.www.lb.Person;
import com.younglibin.www.lb.TestSpring;
public class SpringServletTest extends HttpServlet {
protected void service(HttpServletRequest arg0, HttpServletResponse resp)
throws ServletException, IOException {
// TODO Auto-generated method stub
ServletContext sc = this.getServletContext();
ApplicationContext ac = WebApplicationContextUtils.getWebApplicationContext(sc);
//ApplicationContext ac = new ClassPathXmlApplicationContext("applicationContext.xml");
Person p =(Person)ac.getBean("person");
p.info();
TestSpring ts = (TestSpring)ac.getBean("testSpring");
ts.test();
resp.setCharacterEncoding("UTF-8");
resp.setContentType("test/html");
PrintWriter pw = resp.getWriter();
pw.println("请切换到控制台，查看执行结果.........");
}
}
启动tomcat 测试；
5.用spring管理数据源
参考spring中 “用spring控制JNDI数据源链接”
6.在spring文件中配置了bean 在struts配置中找不到action
1.在工程添加strust2-spring-plugin-*.jar
2.在struts.properties 中 struts.objectFactory = spring 可用
