1.新建数据库表ims-learn.user2.Model包下新建User类注:因为之前初始化项目时添加了lombok依赖,所以model类可以不用写setter/getter,直接使用@Data注解替代3.编写UserDao接口类4.UserMapper.xml<?xmlversion="1.0"encoding="UTF-8"?><!DOCTYPEmapperPUBLIC"-//mybatis.org//DTDMapper3.0//EN""http://mybatis.org/dtd/mybatis-3-mapper.dtd"><mappernamespace="cn.coralcloud.ims.dao.UserDao"><resultMapid="userResultMap"type="User"><idproperty="id"column="id"/><resultproperty="createTime"column="create_time"/><resultproperty="updateTime"column="update_time"/></resultMap><selectid="login"resultMap="userResultMap">select*fromuserwhereemail=#{email}andpassword=#{password}</select></mapper>5.mybatis.xml编写mybatis基础配置,新建resources/mybatis/mybatis.xml<?xmlversion="1.0"encoding="UTF-8"?><!DOCTYPEconfigurationPUBLIC"-//mybatis.org//DTDConfig3.0//EN""http://mybatis.org/dtd/mybatis-3-config.dtd"><configuration><settings><settingname="logImpl"value="STDOUT_LOGGING"/><settingname="lazyLoadingEnabled"value="true"/><settingname="aggressiveLazyLoading"value="false"/><settingname="lazyLoadTriggerMethods"value=""/></settings></configuration>6.UserService.java7.UserController.javapackagecn.coralcloud.ims.controller;importcn.coralcloud.ims.model.User;importcn.coralcloud.ims.service.UserService;importcom.sun.org.apache.xpath.internal.operations.Mod;importorg.springframework.beans.factory.annotation.Autowired;importorg.springframework.stereotype.Controller;importorg.springframework.ui.Model;importorg.springframework.web.bind.annotation.GetMapping;importorg.springframework.web.bind.annotation.PostMapping;importorg.springframework.web.bind.annotation.RequestMapping;importorg.springframework.web.servlet.ModelAndView;importorg.springframework.web.servlet.View;importjavax.servlet.http.HttpSession;/***@authorc-geff*@nameUserController*@description*@date2020-11-0310:45*/@Controller@RequestMapping("/user")publicclassUserController{@AutowiredprivateUserServiceuserService;@PostMapping("/login")publicModelAndViewlogin(Stringemail,Stringpassword,HttpSessionsession){ModelAndViewview=newModelAndView();view.setViewName("user/login");Useruser=userService.login(email,password);if(user!=null){session.setAttribute("AdminUserKey",user);view.setViewName("redirect:/index");returnview;}view.addObject("errmsg","用户名或密码错误!");returnview;}@GetMapping("/login")publicStringlogin(){return"user/login";}}8.login.ftl9.IndexController改造10.index.ftl改造,展示用户登录后的用户名11.数据库添加一条用户数据,然后在/user/login页面登录测试
1.@RestController注解相当于@ResponseBody＋@Controller合在一起的作用。2.如果只是使用@RestController注解Controller，则Controller中的方法无法返回jsp页面，或者html，配置的视图解析器InternalResourceViewResolver不起作用，返回的内容就是Return里的内容。3.如果需要返回到指定页面，则需要用@Controller配合视图解析器InternalResourceViewResolver才行。4.如果需要返回JSON，XML或自定义mediaType内容到页面，则需要在对应的方法上加上@ResponseBody注解。)
汇总节点安装Logstash。Logstash运行需要JDK环境，所以需要首先配置相应JAVA_HOME环境变量。下载与filebeat对应版本压缩包：官网地址根据操作系统选择对应的版本下载解压测试：与Filebeat配置连接，新建beat-logstash.conf：指定配置文件启动logstash（cd$LOGSTASH_HOME）：bin/logstash-fconfig/beat-logstash.conf后台启动使用nohupnohup./bin/logstash-fconfig/beat-logstash.conf--config.reload.automatic>/dev/null2>&1&
采集节点主要安装Filebeat组件即可，Filebeat可以很简单运行在Windows/Linux操作系统上，不需要其余环境。下载Filebeat压缩包:https://www.elastic.co/downloads/past-releases/filebeat-6-2-4根据操作系统选择对应的版本下载解压修改目录下filebeat.yml文件，具体配置下图：上图为filebeat的输入端配置，指定监听文件上图为filebeat的输出端配置，指定输出到本机的Logstash中Filebeat启动（cd$FILEBEAT_HOME）：./filebeat-e-cfilebeat.yml后台启动可使用nohup命令nohup./filebeat-e-cfilebeat.yml-d"publish">logs/filebeat.log2>&1&
