Intellij IDEA 出现"Usage of API documented as @since 1.6+"的解决办法

具体报错内容如下：

This inspection finds all usages of methods that have @since tag in their documentation.  This may be useful when development is performed under newer SDK version as the target platform for production

报错图：

看代码意思是，那个方法是自Java1.6开始的，但是，你的language level 才是5，级别不够，所以，就报错了。

根本的解决办法是在maven中设置编译级别

<properties>
    <java-version>1.7</java-version>
</properties>
<plugins>
    <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-compiler-plugin</artifactId>
        <version>3.2</version>
        <configuration>
            <source>${java-version}</source>
            <target>${java-version}</target>
            <encoding>UTF-8</encoding>
        </configuration>
    </plugin>
</plugins>
