StringMVC程序簡(jiǎn)單實(shí)例
第一步：導(dǎo)入jar包
第二步，在WEB-INF文件夾下創(chuàng)建spring-servlet.xml文件。
?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"
xmlns:aop="http://www.springframework.org/schema/aop"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd
http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd">
!-- 注冊(cè)aop功能 -->
aop:aspectj-autoproxy/>
!-- 自動(dòng)掃面com.springmvc目錄及其子目錄下面所有類文件，自動(dòng)注入所有帶注解的類 -->
context:component-scan base-package="com.yxl.*" />
!-- 處理請(qǐng)求response返回值，如下配置能正確返回字符串型返回值,如返回值為對(duì)象，則自動(dòng)轉(zhuǎn)為json -->
bean id="handleAdapter" class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
property name="messageConverters">
list>
ref bean="mappingJacksonHttpMessageConverter" />!-- json轉(zhuǎn)換器 -->
ref bean="mappingStringHttpMessageConverter" />
/list>
/property>
/bean>
bean id="mappingJacksonHttpMessageConverter" class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter" />
bean id="mappingStringHttpMessageConverter" class="org.springframework.http.converter.StringHttpMessageConverter" />
!-- 對(duì)模型視圖名稱的解析，即在模型視圖名稱添加前后綴 -->
bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
property name="prefix" value="/WEB-INF/jsp/" />
property name="suffix" value=".jsp">/property>
property name="order" value="1">/property>
/bean>
!-- spring文件上傳編碼 -->
bean id="multipartResolver"
class="org.springframework.web.multipart.commons.CommonsMultipartResolver"
p:defaultEncoding="utf-8" />
/beans>
第三步：在web.xml文件配置springmvc。
?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>
!-- 設(shè)置編碼 -->
filter>
filter-name>characterEncodingFilter/filter-name>
filter-class>org.springframework.web.filter.CharacterEncodingFilter/filter-class>
init-param>
param-name>encoding/param-name>
param-value>UTF-8/param-value>
/init-param>
init-param>
param-name>forceEncoding/param-name>
param-value>true/param-value>
/init-param>
/filter>
!-- 配置DispatchcerServlet -->
servlet>
servlet-name>Spring MVC Dispatcher Servlet/servlet-name>
servlet-class>org.springframework.web.servlet.DispatcherServlet/servlet-class>
init-param>
!-- 配置Spring mvc下的配置文件的位置和名稱 -->
param-name>contextConfigLocation/param-name>
param-value>
/WEB-INF/spring-servlet.xml
/param-value>
/init-param>
load-on-startup>1/load-on-startup>
/servlet>
!-- 配置DispatchcerServlet 攔擊路徑'/'所有訪問都攔截-->
servlet-mapping>
servlet-name>Spring MVC Dispatcher Servlet/servlet-name>
url-pattern>//url-pattern>
/servlet-mapping>
/web-app>
第四步：創(chuàng)建一個(gè)控制器。
