当我将spring-boot-starter-actuator依赖项添加到pom.xml时,出现异常“创建名称为'springSecurityFilterChain'的bean时出错”
没有它,项目将正常编译。

最佳答案

我设法通过定义一个实现ErrorController的Controller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,也许您还使用错误的getErrorPath()方法来实现ErrorController。
