在pom.xml文件中添加这个配置

<profiles>
<profile>
  <id>jdk-1.8</id>

  <activation>

    <activeByDefault>true</activeByDefault>

    <jdk>1.8</jdk>

  </activation>

  <properties>

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

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

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

  </properties>

</profile>
</profiles>
<build>
<plugins>
  <plugin>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>3.1</version>
    <configuration>
      <fork>true</fork>
      <executable>
        D:\application\jdk\bin\javac.exe
      </executable>
    </configuration>
  </plugin>
