3.31_myEclipse spring&SpringMVC集成

题首：当你对某项技术熟练的时候。你才会逻辑清晰的表述出来（ps。现在还只是入门阶段。demo版）

一.首先是jar包。搞好spring的就ok

二.随后是搞清楚几点

　　2.1 spring与springMVC的集成，相当于是无缝集成，只要拿到spring需要的jar包就可以用来集成　　　　　　　　　　　　springMVC。

　　2.2 spring是通过listener来加载进web容器的，而springMVC是通过<servlet>加载进来的。

　　2.3 在顺序上，容器加载的顺序为：context---》listener----》filter----》servlet

三.集成步骤

　　3.1 从web.xml文件配置。

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">
  <display-name>springMVC1</display-name>
  <welcome-file-list>
    <welcome-file>index.html</welcome-file>
    <welcome-file>index.htm</welcome-file>
    <welcome-file>index.jsp</welcome-file>
    <welcome-file>default.html</welcome-file>
    <welcome-file>default.htm</welcome-file>
    <welcome-file>default.jsp</welcome-file>
  </welcome-file-list>
  
  <context-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>classpath*:config/springAnnotation-servlet.xml,classpath*:config/springAnnotation-core.xml
      </param-value>
  </context-param>
  
  <listener>
       <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>
  
  
  <servlet>
      <servlet-name>springMVC</servlet-name>
      <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
          <init-param>
              <param-name>contextConfigLocation</param-name>
              <param-value>classpath*:config/springAnnotation-servlet.xml</param-value>
          </init-param> 
      <load-on-startup>1</load-on-startup>
  </servlet>
  
  <servlet-mapping>
      <servlet-name>springMVC</servlet-name>
      <url-pattern>/</url-pattern>
  </servlet-mapping>
</web-app>

　　3.2　spring配置：springAnnotation-core.xml。。。。其中context-param我还是没懂是干啥的。如果不放这个的话ServletContext的默认文件是在WEB-INF下的applicationContext,而我这里指向的xml文件为springAnnotation-core.xml...

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN 2.0//EN" "http://www.springframework.org/dtd/spring-beans-2.0.dtd" [
<!ENTITY contextInclude SYSTEM "org/springframework/web/context/WEB-INF/contextInclude.xml">
]>

<beans>
	<bean id="springManager" class="com.tgb.web.controller.annotation.SpringManager"></bean>
</beans>

　　3.3  springMVC配置：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"  
 xmlns:context="http://www.springframework.org/schema/context"  
 xmlns:p="http://www.springframework.org/schema/p"  
 xmlns:mvc="http://www.springframework.org/schema/mvc"  
 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-3.0.xsd  
      http://www.springframework.org/schema/context  
      http://www.springframework.org/schema/context/spring-context.xsd  
      http://www.springframework.org/schema/mvc  
      http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">
     <!-- 注解扫描包 -->
    <context:component-scan base-package="com.tgb.web.controller.annotation" />
    <!-- 开启注解 -->
    <mvc:annotation-driven/>
    
    <!-- <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter" />
    <bean class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping"></bean> -->
    <!-- 静态资源访问 -->
     <mvc:resources location="/img/" mapping="/img/**"/>  
     <mvc:resources location="/js/" mapping="/js/**"/>   

    <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/"></property>
        <property name="suffix" value=".jsp"></property>
    </bean>
 </beans>  

配置暂时告一段落。下面开始编码，附源码。。

package com.tgb.web.controller.annotation;

public interface ISpring {
    public String get();
}

package com.tgb.web.controller.annotation;

import javax.annotation.Resource;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class SpringController {

    @Resource(name="springManager")
    private ISpring springManger;
    
    @RequestMapping("/spring/get")
    public String get(){
        System.out.println(springManger.get());
        
        return "/success";
    }
    
}

package com.tgb.web.controller.annotation;

public class SpringManager implements ISpring {

    public String get() {
        System.out.println("this is springManager print out!");
        return "i am SpringManager";
    }


}

暂时告一段落
