Question

一点背景：我正在尝试在生产中使用的spring MVC应用中使用spring-boot-actuator。它不是一个spring-boot-application。

我已经用spring-boot-actuator整理了一个简单的spring MVC App。示例代码可用here。克隆和重现错误是一个简单的应用程序。我有README的说明书。

我使用了spring-boot-actuator 1.1.1.RELEASE依赖项，它运行正常。但是，当我想使用1.2.5.RELEASE时，这就是我在容器启动时遇到错误的地方。

SEVERE: StandardWrapper.Throwable

This can happen if you are @ComponentScanning a springframework package (e.g. if you put a @ComponentScan in the default package by mistake)

您使用的是旧版且不兼容的Spring Framework版本。我猜4.0.x。

public interface EmployeeDAO { public void addEmployee(Employee emp); } @Repository public class EmployeeDAOImpl implements EmployeeDAO { public void addEmployee(Employee emp) { /* code here */ } }是Spring Framework 4.1中的新增功能。此外，作为described in the documentation，Spring Boot 1.2.5需要Spring Framework 4.1.5.RELEASE或更高版本。

spring-boot-actuator 1.2.5.RELEASE在容器启动时抛出错误
