spring

使用eclipse maven 构建springMvc helloworld项目

忘记怎么建的话看看

http://limingnihao.iteye.com/blog/830409

写得非常好，需要注意的是

项目-->properties-->Deployment Assembly--> add --> java Build path entry -->把maven加上去

如果不选择这个的话，maven管理的jar包，发布的时候不能发布到tomcat里面去

maven: pom.xml内容

里面的repositories有几个常用的 maven仓库地址

一般找jar包可以先去这几个地址里找到相应的

用得比较多的是 http://search.maven.org/#browse 这个 maven的中心仓库

有些时候通过maven下载下来的jar包是不正确的，如一个包应该是400k，下载下来的才20几k，用不了，这种情况的话就可以直接手动去下载了，然后放到你的仓库对应的包里面去

如果是这个包有问题：

<dependency>
	       <groupId>net.sourceforge.jexcelapi</groupId>
	       <artifactId>jxl</artifactId>
	       <version>${jxl.version}</version>
</dependency>

就到相应maven仓库目录 D:\maven\local\repo (我的)\net\sourceforge\jexcelapi\jxl\版本号

编写Spring配置文件dispatcher-servlet.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"
    xmlns:p="http://www.springframework.org/schema/p" 
    xmlns:context="http://www.springframework.org/schema/context"
    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-3.0.xsd" >

   <context:component-scan base-package="com.loushi135.controller"/>
    
   <!-- 视图解释类org.springframework.web.servlet.view.InternalResourceViewResolver -->  
   <bean class="org.springframework.web.servlet.view.UrlBasedViewResolver">  
    <property name="viewClass" value="org.springframework.web.servlet.view.JstlView" />  
    <property name="prefix" value="/WEB-INF/jsp/"/>  
    <property name="suffix" value=".jsp"/><!--可为空,方便实现自已的依据扩展名来选择视图解释类的逻辑  -->  
   </bean>  
</beans>

编写HelloWorldController

package com.loushi135.controller;

import javax.servlet.http.HttpServletRequest;

import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;


@Controller
@RequestMapping("/hello")
public class HelloWorldController {
	
	@RequestMapping("/helloWorld")
    public ModelAndView helloWorld(ModelAndView mv) {
        String message = "Hello World, Spring 3.0!";
        mv = new ModelAndView("hello", "message", message);
       return mv;
    }
	 
    @RequestMapping("/helloWorld1")
    public String helloWorld1(HttpServletRequest request) {
        String message = "Hello World1111, Spring 3.0!";
        System.out.println(message);
        request.setAttribute("message", message);
       return "hello";//返回视图名hello 将会去找jsp/hello.jsp
    }
	   
    @RequestMapping("/helloWorld2")
    public String helloWorld2(ModelMap mm){
    	String message = "Hello World22222222, Spring 3.0!";
    	mm.addAttribute("message",message);
    	return "hello";
    }
    
}

编写 view (hello.jsp)

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
  <head>
    <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1" />
    <title>${message}</title>
    <link rel="stylesheet" type="text/css" href="./xmlhttp/css/rime/rime.css" />
  </head>
  <body>
    ${message}  
  </body>
</html>

效果：

分别请求

http://localhost:8080/SpringMvcHelloWorld/hello/helloWorld.do

http://localhost:8080/SpringMvcHelloWorld/hello/helloWorld1.do

http://localhost:8080/SpringMvcHelloWorld/hello/helloWorld2.do

其他视图：返回 json,xml,excel,pdf,模板视图等

使用到了返回json的话需要加上spring orm包

<dependency>
	      <groupId>org.springframework</groupId>
	      <artifactId>spring-orm</artifactId>
	      <version>${spring.version}</version>
</dependency>

单独返回json的话：

<bean id="listJson" class="org.springframework.web.servlet.view.json.MappingJacksonJsonView" p:renderedAttributes="jsonData" />

定义一个listJson bean视图返回"listJson"的都是，p:renderedAttributes="jsonData" 这个表示通过modelMap 放进去的attributeName 是这个

json数据是｛jsonData:{name:'123'}｝通过jquery请求时 var name = data.jsonData.name;

单独返回xml的话

<bean class="org.springframework.web.servlet.view.xml.MarshallingView"  p:marshaller-ref="xmlMarshaller"></bean> 
<bean id="xmlMarshaller" class="org.springframework.oxm.xstream.XStreamMarshaller">
		<property name="streamDriver">
			<bean class="com.thoughtworks.xstream.io.xml.StaxDriver"></bean>
		</property>
		<property name="annotatedClasses">
			<list>
				<value>com.loushi135.model.User</value>
			</list>
		</property>
		<!-- 指定使用xstream注解类，在类里设别名  -->
</bean>

使用注解给User类加别名

package com.loushi135.model;

import com.thoughtworks.xstream.annotations.XStreamAlias;
@XStreamAlias("User")
public class User {
	/**
	 *  @XStreamAlias  为别名注解 作用于类或字段
	 *  @XStreamImplicit 隐藏集合类型
	 *  @XStreamOmitField 注解标志java对象的属性不出现在xml中
	 *  @XStreamAsAttribute设置为xml属性
	 *  @XStreamConverter(DateConverter.class) 注入日期转换器
	 */
	@XStreamAlias("name")
	private String name;
	private String password;
	
	public User() {
		super();
		// TODO Auto-generated constructor stub
	}

	public User(String name, String password) {
		super();
		this.name = name;
		this.password = password;
	}

	public String getName() {
		return name;
	}

	public void setName(String name) {
		this.name = name;
	}

	public String getPassword() {
		return password;
	}

	public void setPassword(String password) {
		this.password = password;
	}
	
}

混合多种视图技术

以不同的MIME格式获取不同资源

 <bean class="org.springframework.web.servlet.view.BeanNameViewResolver" p:order="0" ></bean>

<!-- 混合多种视图技术 -->
	<bean class="org.springframework.web.servlet.view.ContentNegotiatingViewResolver"
		  p:order="1"
		  p:defaultContentType="text/html"
		  p:ignoreAcceptHeader="true"
		  p:favorPathExtension="false"
		  p:favorParameter="true"
		  p:parameterName="content"
	>
		<property name="mediaTypes">
			<map>
				<entry key="html" value="text/html"></entry>
				<entry key="xml" value="application/xml"></entry>
				<entry key="json" value="application/json"></entry>
			</map>
		</property>
		<property name="defaultViews">
			<list>
				<bean class="org.springframework.web.servlet.view.json.MappingJacksonJsonView" p:renderedAttributes="jsonData"></bean>
				<bean class="org.springframework.web.servlet.view.xml.MarshallingView" p:modelKey="xmlData" p:marshaller-ref="xmlMarshaller"></bean> 
				<!-- <bean class="com.loushi135.view.UserListExcelView"></bean> -->
			</list>
		</property>
	</bean>
	<bean id="xmlMarshaller" class="org.springframework.oxm.xstream.XStreamMarshaller">
		<property name="streamDriver">
			<bean class="com.thoughtworks.xstream.io.xml.StaxDriver"></bean>
		</property>
		<property name="annotatedClasses">
			<list>
				<value>com.loushi135.model.User</value>
			</list>
		</property>
		<!-- 指定使用xstream注解类，在类里设别名  -->
	</bean>
   <!-- 视图解释类org.springframework.web.servlet.view.InternalResourceViewResolver -->  
    <bean class="org.springframework.web.servlet.view.UrlBasedViewResolver"  p:order="100" >  
    	<property name="viewClass" value="org.springframework.web.servlet.view.JstlView" />  
    	<property name="prefix" value="/WEB-INF/jsp/"/>  
    	<property name="suffix" value=".jsp"/><!-- 可为空,方便实现自已的依据扩展名来选择视图解释类的逻辑  -->  
    </bean> 
    <bean id="userListExcelView" class="com.loushi135.view.UserListExcelView"></bean>
    <bean id="userListPoiExcelView" class="com.loushi135.view.UserListPoiExcelView"></bean>
    <bean id="userListPdfView" class="com.loushi135.view.UserListPdfView"></bean>
    <!-- 使用 BeanNameViewResolver  返回视图'userListExcelView'就进入userListExcelView处理 -->

BeanNameViewResolver 使用bean id作为视图解析器如上面的 userListExcelView等

p:order 这是给视图解析设置排序的，值小的先匹配

p:parameterName="content" 设置前台请求传过来的mime类型的参数如'url?content=json'

property mediaTypes里的 key是content=json里的json. value是'application/json' 在相应的视图解析器里都有对应的

如AbstractExcelView，AbstractJExcelView 里对应的是"application/vnd.ms-excel" 返回excel的视图

AbstractPdfView则对应的是"application/pdf"

MappingJacksonJsonView对应的是"application/json"

MarshallingView对应的是"application/xml"
