Beans（beans）

beans 端点提供有关应用程序 Bean 的信息。

获取 Bean 列表

要获取 Bean 信息，请对 /actuator/beans 发起 GET 请求，如下所示（基于 curl 的示例）：

$ curl 'http://localhost:8080/actuator/beans' -i -X GET

返回的响应类似如下：

HTTP/1.1 200 OK
Content-Type: application/vnd.spring-boot.actuator.v3+json
Content-Length: 1089

{
  "contexts" : {
    "application" : {
      "beans" : {
        "org.springframework.boot.autoconfigure.web.servlet.DispatcherServletAutoConfiguration$DispatcherServletRegistrationConfiguration" : {
          "aliases" : [ ],
          "scope" : "singleton",
          "type" : "org.springframework.boot.autoconfigure.web.servlet.DispatcherServletAutoConfiguration$DispatcherServletRegistrationConfiguration",
          "dependencies" : [ ]
        },
        "org.springframework.boot.autoconfigure.context.PropertyPlaceholderAutoConfiguration" : {
          "aliases" : [ ],
          "scope" : "singleton",
          "type" : "org.springframework.boot.autoconfigure.context.PropertyPlaceholderAutoConfiguration",
          "dependencies" : [ ]
        },
        "org.springframework.boot.autoconfigure.web.servlet.DispatcherServletAutoConfiguration" : {
          "aliases" : [ ],
          "scope" : "singleton",
          "type" : "org.springframework.boot.autoconfigure.web.servlet.DispatcherServletAutoConfiguration",
          "dependencies" : [ ]
