Question

使用jdk 1.8和spring 4.2.5版本，我的项目在maven编译中失败

我在pom.xml中也添加了依赖项高级谢谢

Answer 1

Compatibility Guide for JDK 8表示java 1.8中java编译器（javac）的变化。详细信息可以在本文档中的“在编译其实现时需要存在接口”的概要中找到。因此，在使用JDK 8时，必须在编译过程中将具有缺少接口的类添加到类路径中。

我已添加此依赖项来解决此问题。

<dependency>
            <groupId>com.ibm.ws.prereq</groupId>
            <artifactId>commonj-twm</artifactId>
            <version>8.0.0</version>
            <scope>provided</scope>
        </dependency>
