当我将spring-boot-starter-actuator依赖项添加到我的 pom.xml 时，我得到一个异常“错误创建名称为'springSecurityFilterChain'的bean” 没有它项目编译正常。

我通过定义一个实现 ErrorController 的控制器并使 getErrorPath() 返回 null 来重现异常：

@Controller
public class MyErrorController implements ErrorController {

    @RequestMapping("/whatever")
    public String myMethod(HttpServletRequest request, HttpServletResponse response) {
        return "hello.html";
    }

    @Override
    public String getErrorPath() {
        return null;
    }
}

因此，也许您也在使用错误的 getErrorPath() 方法实现 ErrorController。
