【问题描述】：
我正在尝试使用 REST Assured v4.3.0 测试在我的控制器类中定义的 REST api，但是在运行测试时我得到了 java.lang.AbstractMethodError。我知道这个错误正在发生，因为我正在调用一个抽象方法，但我很难解决它。
似乎由于SampleControllerTest.java 中的.body(is(equalTo("success"))) 而发生错误，因为当我删除此行时，测试成功。我尝试了一些方法来解决它，但没有成功：
- 在线搜索建议和示例，但它们要么是旧版本，要么与
io.rest-assured/spring-mock-mvc无关 - 尝试了不同的匹配器（
org.hamcrest.Matchers.*和org.hamcrest.CoreMatchers.*） - 尝试在 pom 文件中显式添加
org.hamcrest/hamcrest依赖项
这是我的代码供您参考：
代码结构：
