先简单说一下我们工程的架构:前端工程是采用react,后端工程采用spring-cloud,里面分为zuul工程和其他功能模块。zuul工程除了提供后端的路由转发,还可以做全局的过滤器,所以我选择在这个工程里面写登陆校验功能。
session配置
这里使用redis存储session信息。
下载依赖,在pom.xml里面加入
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-data-redis</artifactId></dependency><dependency> <groupId>org.springframework.session</groupId> <artifactId>spring-session-data-redis</artifactId></dependency>
配置session存储,在application.yml里面加入
session: store-type: redis timeout: 30redis: database: 0 host: password: port: 6379 timeout: 300000
session超时,在application.yml里面配置timeout貌似没有效果,我们在启动类里面加入超时配置注解
复制代码代码如下:
@EnableRedisHttpSession(maxInactiveIntervalInSeconds = 7200, redisFlushMode = RedisFlushMode.IMMEDIATE)
添加redis类配置,新建一个redisConfig类,然后写入
package com.config;import org.springframework.context.annotation.Configuration;@Configurationpublic class RedisConfig { public RedisConfig() { }}
过滤器
这里使用zuulFilter,实现了每个http请求都经过这个过滤器,然后通过session中是否存在用户名,判断session是否超时。如果超时就返回错误提示,前端再根据超时的http请求码进行跳转。
package com.config;import com.netflix.zuul.ZuulFilter;import com.netflix.zuul.context.RequestContext;import com.ztesoft.cloud.Service.StaffService;import com.ztesoft.cloud.model.User;import org.springframework.beans.factory.annotation.Autowired;import javax.servlet.http.HttpServletRequest;public class WebSecurityFilter extends ZuulFilter { @Override public String filterType() { return "pre";//前置过滤器 } @Override public int filterOrder() { return 0;//优先级为0,数字越大,优先级越低 } @Override public boolean shouldFilter() { return true;//是否执行该过滤器,此处为true,说明需要过滤 } @Autowired private StaffService staffService; @Override public Object run() { RequestContext ctx = RequestContext.getCurrentContext(); HttpServletRequest request = ctx.getRequest(); String queryString = request.getQueryString(); Object username = request.getSession().getAttribute("username"); Object password = request.getSession().getAttribute("password"); User user = new User(); if(username != null) { user.setUsername(username.toString()); } if(password != null) { user.setPassword(password.toString()); } Boolean verifyResult = this.staffService.verifyLoginUser(user); if ((queryString != null && queryString.indexOf("tag=process") > -1) || verifyResult) { ctx.setSendZuulResponse(true);// 对该请求进行路由 ctx.setResponseStatusCode(200); ctx.set("isSuccess", true);// 设值,可以在多个过滤器时使用 return null; } else { ctx.setSendZuulResponse(false);// 过滤该请求,不对其进行路由 ctx.setResponseStatusCode(401);// 返回错误码,应该是401 ctx.setResponseBody("session is out of time");// 返回错误内容 ctx.set("isSuccess", false); return null; } }}
这里还需要在启动类中注入这个类
@Bean public WebSecurityFilter accessFilter() { return new WebSecurityFilter(); }
登陆的代码
主要就是把前端传来的用户名密码放到session中,并进行校验。如果校验成功,返回登陆成功,否则,返回登陆失败。前端再根据登陆情况做路由跳转。
package com.controller;@RestController@RequestMapping(value = "/system")public class SystemController extends JdkSerializationRedisSerializer implements Serializable { @Autowired private StaffService staffService; @PostMapping("login") public ResponseEntity<String> login(@RequestBody User user, HttpSession session) { session.setAttribute("username", user.getUsername()); session.setAttribute("password", user.getPassword()); Boolean ret = this.staffService.verifyLoginUser(user); if(ret == true) { return new ResponseEntity<>("登陆成功", HttpStatus.OK); } return new ResponseEntity<>("登陆失败", HttpStatus.NON_AUTHORITATIVE_INFORMATION); }}
最后,贴一下启动类的代码
@SpringBootApplication@EnableDiscoveryClient@EnableZuulProxy@EnableRedisHttpSession(maxInactiveIntervalInSeconds = 7200, redisFlushMode = RedisFlushMode.IMMEDIATE)@ComponentScan(excludeFilters = @ComponentScan.Filter(type = FilterType.ASSIGNABLE_TYPE, value = RibbonConfig.class))@RibbonClients(defaultConfiguration = RibbonConfig.class)public class PlatformWebApplication { @Bean public WebSecurityFilter accessFilter() { return new WebSecurityFilter(); } public static void main(String[] args) { SpringApplication.run(PlatformWebApplication.class, args); }}
