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: 30 redis: 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
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;
@Configuration
public 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);
}
}
