解决方法：

        看Eclipse-->Window-->preferences-->Java-->Installed JREs

如果你打开后已经选中了jdk则不需要处理，如果是jre的话，就点击add

点击next，选择你的jdk的位置，最后finish

最后选中jdk,下面的jre也可以删掉

我们看看Maven的环境是如何配置的:先找到Eclipse-->Window-->preferences-->Maven-->Installations

 

在Maven配置中, 我并没有使用Eclipse自带的Maven插件, 而是重新配置的Maven环境, 然后再看Eclipse-->Window-->preferences-->Maven-->User Settings

 

Maven设置使用的是Maven中conf文件夹下的settings.xml

在180行左右的profiles标签内加入这么一段话

1. <profile>

2. <id>jdk-1.8</id>

3. <activation>

4. <activeByDefault>true</activeByDefault>

5. <jdk>1.8</jdk>

6. </activation>

7. <properties>

8. <maven.compiler.source>1.8</maven.compiler.source>

9. <maven.compiler.target>1.8</maven.compiler.target>

10. <maven.compiler.compilerVersion>1.8</maven.compiler.compilerVersion>

11. </properties>

12. </profile>

在项目上右键Build Path，进入

然后再编译运行项目即可.
