SpringSecurityFilterChain & Actuator
SpringSecurityFilterChain & Actuator
当我将 spring-boot-starter-actuator 依赖项添加到 pom.xml 时,出现异常 "Error creating bean with name 'springSecurityFilterChain'"
没有它项目编译正常。

我通过定义实现 ErrorController 的控制器并使 getErrorPath() return 为 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;
}
}
所以也许您也在使用错误的 getErrorPath() 方法实现 ErrorController。
