关于Spring.io官网Spring Session Restful example的问题

问题描述

当使用SpringBoot提供Restful接口服务时，可以非常方便快速地通过SpringBoot来发布。然而需要考虑的问题：

• 使用安全机制
• 使用外在数据库保存session

针对安全机制，官网提供了一个demo：
官网demo地址为：http://docs.spring.io/spring-session/docs/current/reference/html5/guides/rest.html
然而该demo，还是存在两个问题：

• 每次authentication都不能正常验证
• 该demo使用而是嵌入式的redis server数据库

解决方案

添加外在Redis数据库

在src/main/resources/application.properties 添加如下配置内容：

# REDIS (RedisProperties)
spring.redis.host=10.10.2.176
spring.redis.port=6379
spring.redis.pool.max-idle=8
spring.redis.pool.min-idle=0
spring.redis.pool.max-active=8
spring.redis.pool.max-wait=-1

这样就可以在代码中设置Redis Server的地址和端口了。
代码结构如下：

具体代码如下，我对HttpSessionConfig.java获取Redis Server的部分进行了更改，从而可以使用external redis server。此外对我build.gradle的security依赖部分进行了改动，如下所示：

    // security related
    compile('org.springframework.boot:spring-boot-starter-security:1.2.2.RELEASE')
    //compile('org.springframework.security:spring-security-config:3.2.6.RELEASE')
    //compile('org.springframework.security:spring-security-web:3.2.6.RELEASE')

public class HttpSessionInitializer extends AbstractHttpSessionApplicationInitializer {
    // this will help initialize and load HttpSessionConfig class, this ensures that out
    // servlet container (ie. tomcat) uses the springSessionRepositoryFilter for every
    // request
    public HttpSessionInitializer() {
        super(HttpSessionConfig.class);
