老师你好，我在引入Spring Session框架后，项目后台报错，但是能够正常访问http://localhost:8080

我的pom文件

Spring版本已经改为4.0.3.RELEASE
RedissonManager代码

package com.mmall.common;

import com.mmall.util.PropertiesUtil;
import lombok.extern.slf4j.Slf4j;
import org.redisson.Redisson;
import org.redisson.config.Config;
import org.springframework.stereotype.Component;
import javax.annotation.PostConstruct;

@Component
@Slf4j
public class RedissonManager {

    private Config config = new Config();

    private Redisson redisson = null;

    private static String  redis1Ip = PropertiesUtil.getProperty("redis1.ip");
    private static Integer redis1Port = Integer.parseInt(PropertiesUtil.getProperty("redis1.port"));
    private static String  redis2Ip = PropertiesUtil.getProperty("redis2.ip");
    private static Integer redis2Port = Integer.parseInt(PropertiesUtil.getProperty("redis2.port"));

    public Redisson getRedisson() {
        return redisson;
    }

    @PostConstruct
    private void init() {
        try {
            config.useSingleServer().setAddress(new StringBuilder().append(redis1Ip).append(":").append(redis1Port).toString());
            redisson = (Redisson) Redisson.create(config);
            log.info("初始化Redisson结束");
        } catch (Exception e) {
           log.error("redisson init error",e);
        }
    }
}
