org.springframework.data.redis.RedisConnectionFailureException

 

错误信息： 

Maven一个项目 执行Update Project后报错One or more constraints have not been satisfied.Spring 4.1 requires Java 1.6 or newer

此错误的意思为 Springg4.1版本的框架 需要JDK1.6以上版本的编译。

此时项目为 JavaSE-1.5版本

项目右键 > Bulid Path >Counfigure Build Path   选择1.7版本JDK 后执行Update Project 仍报错，变回原来1.5版本的JDK。（此方式解决失效）

解决方式 一

在pom.xml 文件中指定jdk版本信息 

 
    
      
        maven-compiler-plugin
        
          1.7
          1.7
        
      
    
  

解决方式 二

删除原来项目，新建Maven项目，指定jdk版本为1.7以上。

错误的原因在于redis配置文件多了个空格
