1.配置spring-mvc.xml
自動掃描控制器，檢視模式，註解的啟動
<?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:mvc="http://www.springframework.org/schema/mvc" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd"> <!-- 自動掃描該包，使SpringMVC認為包下用了@controller註解的類是控制器 --> <context:component-scan base-package="cxc.hotel.Controller" /> <mvc:default-servlet-handler/> <!--避免IE執行AJAX時，返回JSON出現下載檔案 --> <bean id="mappingJacksonHttpMessageConverter" class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter"> <property name="supportedMediaTypes"> <list> <value>text/html;charset=UTF-8</value> </list> </property> </bean> <!-- 啟動SpringMVC的註解功能，完成請求和註解POJO的對映 --> <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"> <property name="messageConverters"> <list> <ref bean="mappingJacksonHttpMessageConverter" /> <!-- JSON轉換器 --> </list> </property> </bean> <!-- 定義跳轉的檔案的前後綴 ，檢視模式配置--> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <!-- 這裡的配置我的理解是自動給後面action的方法return的字串加上字首和字尾，變成一個 可用的url地址 --> <property name="prefix" value="/WEB-INF/jsp/" /> <property name="suffix" value=".jsp" /> </bean> <!-- 配置檔案上傳，如果沒有使用檔案上傳可以不用配置，當然如果不配，那麼配置檔案中也不必引入上傳元件包 --> <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"> <!-- 預設編碼 --> <property name="defaultEncoding" value="utf-8" /> <!-- 檔案大小最大值 --> <property name="maxUploadSize" value="10485760000" /> <!-- 記憶體中的最大值 --> <property name="maxInMemorySize" value="40960" /> </bean> </beans>
2.配置web.xml這裡面對spring-mybatis.xml的引入以及配置的spring-mvc的Servlet就是為了完成SSM整合
<?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" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" version="3.0"> <display-name>Archetype Created Web Application</display-name> <!-- Spring和mybatis的配置檔案 --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring-mybatis.xml</param-value> </context-param> <!-- 編碼過濾器 --> <filter> <filter-name>encodingFilter</filter-name> <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> <async-supported>true</async-supported> <init-param> <param-name>encoding</param-name> <param-value>UTF-8</param-value> </init-param> </filter> <filter-mapping> <filter-name>encodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- Spring監聽器 --> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- 防止Spring記憶體溢位監聽器 --> <listener> <listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class> </listener> <!-- Spring MVC servlet --> <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:spring-mvc.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> <async-supported>true</async-supported> </servlet> <servlet-mapping> <servlet-name>SpringMVC</servlet-name> <!-- 此處可以可以配置成*.do，對應struts的字尾習慣 --> <url-pattern>/</url-pattern> </servlet-mapping> <welcome-file-list> <welcome-file>/index.jsp</welcome-file> </welcome-file-list> </web-app>
3.測試
3.0）建index.jsp
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>Insert title here</title> </head> <body> hello </body> </html>
3.1）showUser.jsp
<%@ page language="java" contentType="text/html; charset=UTF-8" import="java.util.*"
pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<title>測試</title>
</head>
<body>
${user.userName}
</body>
</html>3.2）UserController.java控制類
package cxc.hotel.controller;
import javax.annotation.Resource;
import javax.servlet.http.HttpServletRequest;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import cxc.hotel.entity.User;
import cxc.hotel.service.UserService;
@Controller
@RequestMapping("/user")
public class UserController {
@Resource
private UserService userService;
@RequestMapping("/showUser")
public String toIndex(HttpServletRequest request,Model model){
int userId = Integer.parseInt(request.getParameter("id"));
System.out.println("11111111111111111111222222222222222222222222+id");
User user = this.userService.getUserById(userId);
System.out.println("11111111111111111111222222222222222222222222");
model.addAttribute("user", user);
return "showUser";
}
}
3.4）部署專案
3.4.1）部署專案後，預設進入開始設定的首頁index.jsp
正確
3.4.2）但當我輸入http://localhost:8080/Hotel/user/showUser.do?id=1時候，報出以下錯誤
在網上搜索，說沒有ojdbc驅動包，但是我自己匯入的ojdbc驅動包了啊。
最後發現自己雖然匯入ojdbc這個jar包，junit測試的時候也確實使用了該jar包，但是在部署專案的時候，這個jar包沒有加入到專案中，所以需要我們手動加入，如圖，在WEB-INF下面建lib檔案用於存放ojdbc的jar包：
3.4.3）再次測試，成功
4.貼上完整的專案結構圖
5.完整的專案程式碼下載（百度雲）：點選下載
