學習整合hibernate springmvc spring的心得(3)

上面構建了兩篇寫了該有的方法也就是說準備工作準備好了

下面我是將創建一個jsp文件夾，將他放入web-inf下這意味着jsp頁面都需要控制器跳轉才能訪問

很有必要先展示下我的文件結構

下面是web.xml的代碼

<?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>SSH_USER</display-name>
  <!-- opsessioninview -->
  <filter>
    <filter-name>openSessionInview</filter-name>

    <init-param>
      <param-name>sessionFactoryBeanName</param-name>
      <param-value> sessionFactory</param-value>
    </init-param>

  </filter>
  <filter-mapping>
    <filter-name>encodingFilter</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>
  <!-- 驗證用戶是否登錄 -->
  <filter>
    <filter-name>LoginFilter</filter-name>
    <filter-class>com.caicai.interceptor.MyLoginFilter</filter-class>
  </filter>

<error-page>
   <error-code>404</error-code>
    <location>/error2.jsp</location>
</error-page>
</web-app>

以下是springmvc的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"

            http://www.springframework.org/schema/context/spring-context-3.0.xsd">
<!-- 啓用註解 --> 
<mvc:annotation-driven/>          
<!--使Spring支持自動檢測組件，如註解的Controller-->
<context:component-scan base-package="com.minx.crm.web.controller"/>
<!-- 掃描註解包 掃描controller-->
<context:component-scan base-package="com.caicai.web.controller"/>

<!-- 配置視圖解析器 -->
<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
          <!-- 前綴 -->
          <property name="prefix" value="/WEB-INF/jsp/"></property>
          <!--<property name="prefix" value="/"></property>-->
          <!-- 後綴 -->
          <property name="suffix" value=".jsp"></property>
 </bean>
 
 <!-- 配置文件解析器 -->
 <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
       <property name="defaultEncoding" value="UTF-8"></property>
       <property name="maxUploadSize" value="10485760000"></property>
       <property name="maxInMemorySize" value="40960"></property>
 </bean>  
 <!-- 這個請求不過濾 比如靜態資源-->    
 <mvc:resources location="/Images/" mapping="/Images/**"/>  
 <mvc:resources location="/bootstrap/" mapping="/bootstrap/**"/>
 <mvc:resources location="/css/" mapping="/css/**"/>

 <!-- 國際化 -->
 <bean id="messageSource"
    class="org.springframework.context.support.ResourceBundleMessageSource"
    p:basename="message">
</bean> 

<!-- 攔截器 -->
<mvc:interceptors>
    <mvc:interceptor>
        <mvc:mapping path="/User/findbypage" />
        <mvc:mapping path="/User/beforeupdate" />
        <mvc:mapping path="/User/update" />
        <mvc:mapping path="/User/delete" />
        <mvc:mapping path="/User/photoupload" />
        <bean class="com.caicai.interceptor.MyInteceptorfindbypage" />
    </mvc:interceptor>
 </mvc:interceptors>
</beans>

至此配置算是完事了

然後可以寫控制器了

這裏就寫登錄爲例子

package com.caicai.web.controller;

import java.io.File;
import java.io.IOException;
import java.io.PrintWriter;
import java.util.Date;
import java.util.List;
import java.util.Set;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.apache.commons.io.FileUtils;
import org.hibernate.Hibernate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.multipart.MultipartFile;

import com.alibaba.fastjson.JSONArray;
import com.alibaba.fastjson.JSONObject;
import com.caicai.entity.Authority;
import com.caicai.entity.Group;
import com.caicai.entity.Information;
import com.caicai.entity.Role;
import com.caicai.entity.User;
import com.caicai.service.inter.GroupServiceinter;
import com.caicai.service.inter.RoleServiceinter;
import com.caicai.service.inter.UserServiceinter;
@Controller
@RequestMapping("/User")
public class UserController {
	@Autowired
	private UserServiceinter userService;
	@Autowired
	private RoleServiceinter roleService;
	@Autowired
	private GroupServiceinter groupService;
	 @RequestMapping("/logincheck")
	 public void logincheck(User u,String code,HttpServletRequest request,HttpServletResponse response) 
	 {	   
		 //String path=request.getSession().getServletContext().getRealPath("/Images/lin.gif");
		 //System.out.println("path"+path);
		 User ru=this.userService.Userlogin(u);
		 String randStr=(String) request.getSession().getAttribute("randStr");
		 String json="";
		 if(ru==null||!code.equals(randStr))
		 {
			 json="登錄失敗";
		 }
		 else
		 {
			 json="登錄成功";
			 Hibernate.initialize(ru.getUrole().getAuthoritys());
			 Hibernate.initialize(ru.getUgroup());
			 request.getSession().setAttribute("user", ru);
			 //對權限初始化 取消懶加載,關聯的關聯 我也不知道爲什麼opensessioninview不好用
		     //request.getSession().setAttribute("As", ru.getUrole().getAuthoritys());
			/*Set<Authority> list=(Set<Authority>)ru.getUrole().getAuthoritys();
			   System.out.println("listsize"+list.size());*/			 
		 }
		 response.setContentType("application/json; charset=utf-8");  
		 JSONObject jo=new JSONObject();
		 jo.put("json", json);
		 PrintWriter out = null;  
		 try {
			 out = response.getWriter();
			 out.write(jo.toString());
		} catch (IOException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}  
		 finally{
			 if(out != null) {  
				    out.flush();
		            out.close();  
		    } 
		 }
	 } }

登錄頁面省略至此框架算是搭建完畢了

細節方面以後會繼續發博客寫的
