昨天完善和完整了表格的代码和大部分功能，比如点击详情跳转社团详情页面和点击申请能发送申请表单，今天准备完善之前未完善的部分，例如拦截器的设置和上传头像功能的实现，拦截器我是在配置文件中设置了一个

<mvc:interceptors>
<mvc:interceptor>
<mvc:mapping path="/**" />
<mvc:exclude-mapping path="/login" />
<mvc:exclude-mapping path="/logout.html" />
<mvc:exclude-mapping path="/register" />
<mvc:exclude-mapping path="/active" />
<mvc:exclude-mapping path="/statics/**" />
<bean class="com.atguigu.crud.lanjieqi.LoginInterceptor"></bean>
</mvc:interceptor>
<mvc:interceptor>
<mvc:mapping path="/**" />
<mvc:exclude-mapping path="/login" />
<mvc:exclude-mapping path="/user/edit2" />
<mvc:exclude-mapping path="/logout.html" />
<mvc:exclude-mapping path="/user/edit" />
<mvc:exclude-mapping path="/register" />
<mvc:exclude-mapping path="/active" />
<mvc:exclude-mapping path="/statics/**" />
<bean class="com.atguigu.crud.lanjieqi.CompleteInfoInterceptor"></bean>
</mvc:interceptor>
</mvc:interceptors>

然后配置拦截所有的请求除了一些登录和注册之类的请求，之前不知道怎么回事死活弄不出来，后来也不知道怎么弄得就突然好了，可能是我设置拦截器的时候把一些请求给拦截了，这是拦截器的后端代码：

package com.atguigu.crud.lanjieqi;

import org.springframework.web.servlet.handler.HandlerInterceptorAdapter;

import com.atguigu.crud.bean.User;

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

public class CompleteInfoInterceptor extends HandlerInterceptorAdapter {

@Override
public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler)
throws Exception {
User user = (User) request.getSession().getAttribute("user");
// 如果有用户信息，并且昵称为null，说明没有完善个人资料
if (user != null && user.getNick_name() == null) {
response.sendRedirect(request.getContextPath() + "/user/edit?action=change");
return false;// 拦截
}
return true;
}
}

和

package com.atguigu.crud.lanjieqi;

import org.springframework.web.servlet.handler.HandlerInterceptorAdapter;

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

public class LoginInterceptor extends HandlerInterceptorAdapter {

@Override
public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler)
throws Exception {
Object user = request.getSession().getAttribute("user");
if (user == null) {
response.sendRedirect(request.getContextPath() + "/login.jsp");
return false;
}
return true;
}
}

拦截器算是已经完善了，现在还未完善的功能就是修改头像。
