Spring session + spring security practice of microservice non-login service

Configuration

When I haven't used spring session yet, I have never understood how to make the backend actively store the session in the persistence layer (such as redis). After reading the spring session documentation and blog these days, I understand it. Simply put, it is the following A passage:

Spring Session creates a Spring bean with the name of springSessionRepositoryFilter that implements Filter. The filter is in charge of replacing the HttpSession implementation to be backed by Spring Session.

However , the configuration tutorial on the spring.io official website is really not good. It is impossible to insert data into redis when it is configured , and the demo given cannot be run on this machine.
Now give my configuration scheme

rely

<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>

application.properties

# 必须要加，否则你加依赖不加这个连启动都报错
spring.session.store-type=redis
# 默认为localhost:6379，可以通过配置更改
spring.redis.host=localhost
# Redis server password
# 如果密码为空，就不要写了，否则也报错
# spring.redis.password=
# Redis server port.
spring.redis.port=6379
# 指定储存的位置
spring.session.redis.namespace=redis:session
spring.session.redis.flush-mode=immediate
spring.session.timeout=5m
# 超时断连，不指定可能会报unable to connect to redis
spring.redis.timeout=3000

View redis

Send any request, and then check the keys * on redis, you can see the saved session

Configure spring security

As a non-login side, the security configuration does not need to be complicated, only a simple securityConfig class is needed

Introduce dependencies

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-security</artifactId>
        </dependency>

SecurityConfig class

package com.ilife.weiboservice.config;

import org.springframework.security.config.annotation.method.configuration.EnableGlobalMethodSecurity;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;


@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {
    
    

    @Override
    protected void configure(HttpSecurity http) throws Exception {
    
    
        http.authorizeRequests()
                .anyRequest().authenticated()
                .and()
                .csrf().disable();
    }
}

controller

For the interface to be protected, @PreAuthorize needs to be annotated as follows

    @ApiOperation(notes = "Get all Weibos from database of one user specified by userID", value = "get one user's Weibos", httpMethod = "GET")
    @RequestMapping(path = "/weibo/getWeibos")
    @PreAuthorize("hasRole('ROLE_USER')")
    public List<Weibo> getWeibos(@ApiParam(name = "userId", value = "The user ID of a WeiBo user,should be a Long Integer") @RequestParam("userId") Long uid) {
    
    
        System.out.println("********** getWeibos **********");
        return weiboService.findAllByUid(uid);
    }
