Spring Boot异步发送邮件

用户登录流程图：

在spring拦截器中进行鉴权操作：

控制器的拦截：

import com.mooc.house.common.model.User;
import org.springframework.stereotype.Component;
import org.springframework.web.servlet.HandlerInterceptor;
import org.springframework.web.servlet.ModelAndView;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.net.URLEncoder;

@Component  //成为spring ben
public class AuthActionInterceptor implements HandlerInterceptor {
    @Override
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object o)
            throws Exception {
        User user= UserContext.getUser();
        if(user==null){ //重定向到登录界面
            String msg= URLEncoder.encode("请先登录","utf-8");
            String target = URLEncoder.encode(request.getRequestURL().toString(),"utf-8");
            if ("GET".equalsIgnoreCase(request.getMethod())) {
                response.sendRedirect("/accounts/signin?errorMsg=" + msg + "&target="+target);
                return false;
            }else {
                response.sendRedirect("/accounts/signin?errorMsg="+msg);
                return false;
            }
        }
        return false;
    }

    @Override
    public void postHandle(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Object o, ModelAndView modelAndView) throws Exception {

    }

    @Override
    public void afterCompletion(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Object o, Exception e) throws Exception {

    }
}

　　

import com.google.common.base.Joiner;
import com.mooc.house.common.constants.CommonConstants;
import com.mooc.house.common.model.User;
import org.springframework.stereotype.Component;
import org.springframework.web.servlet.HandlerInterceptor;
import org.springframework.web.servlet.ModelAndView;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;
import java.util.Map;

@Component  //实现拦截器接口
public class AuthInterceptor implements HandlerInterceptor {
    @Override  //在控制器执行之前拦截执行的
    public boolean preHandle(HttpServletRequest request, HttpServletResponse httpServletResponse, Object o)
            throws Exception {
        Map<String,String[]> map=request.getParameterMap(); //获取所有的请求
        map.forEach((k,v)->{
            if (k.equals("errorMsg") || k.equals("successMsg") || k.equals("target")) {
                request.setAttribute(k, Joiner.on(",").join(v));
            }
        });
        String reqUri=request.getRequestURI();
        if(reqUri.startsWith("/static")||reqUri.startsWith("/error")){
            return true;
        }
        HttpSession session=request.getSession(true);  //没有的话创建
        User user=(User)session.getAttribute(CommonConstants.USER_ATTRIBUTE);
        if(user!=null){
            UserContext.setUser(user);
        }
        return true;
    }

    @Override
    public void postHandle(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Object o, ModelAndView modelAndView) throws Exception {

    }

    @Override
    public void afterCompletion(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Object o, Exception e) throws Exception {
         UserContext.remove();
    }
}

　　获取删除得到用户信息：

public class UserContext {
    private static  final  ThreadLocal<User> USER_THREAD_LOCAL=new ThreadLocal<>();
    public static  void setUser(User user){
        USER_THREAD_LOCAL.set(user);
    }
    public static  void remove(){
        USER_THREAD_LOCAL.remove();
    }
    public static User getUser(){
        return USER_THREAD_LOCAL.get();
    }
}

　　注册到请求接口：

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.InterceptorRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;

@Configuration
public class WebMvcConf  extends WebMvcConfigurerAdapter {
    @Autowired
    private  AuthActionInterceptor authActionInterceptor;

    @Autowired
    private AuthInterceptor authInterceptor;
    //管理拦截请求
    @Override
    public void addInterceptors(InterceptorRegistry registry){
        registry.addInterceptor(authInterceptor).excludePathPatterns("/static").addPathPatterns("/**");
        registry
                .addInterceptor(authActionInterceptor).addPathPatterns("/house/toAdd")
                .addPathPatterns("/accounts/profile").addPathPatterns("/accounts/profileSubmit")
                .addPathPatterns("/house/bookmarked").addPathPatterns("/house/del")
                .addPathPatterns("/house/ownlist").addPathPatterns("/house/add")
                .addPathPatterns("/house/toAdd").addPathPatterns("/agency/agentMsg")
                .addPathPatterns("/comment/leaveComment").addPathPatterns("/comment/leaveBlogComment");
        super.addInterceptors(registry);
    }
}

　　拦截器编写配置步骤：

在配置中加入：

domain.name=127.0.0.1:8090

spring.mail.host=smtp.163.com
spring.mail.username=
spring.mail.password=
spring.mail.properties.mail.smtp.outh=true
spring.mail.properties.mail.smtp.starttls.enable=true
spring.mail.properties.mail.smtp.starttls.required=true
