当我在shiro中使用Spring Boot时，Spring Boot执行器不发布jvm度量

Question

我将Spring Boot与Shiro一起使用,但我启动应用程序并导航到/acture/metrics时会显示可用仪表名称的列表：

{
    names: [
        "http.server.requests",
        "jdbc.connections.max",
        "jdbc.connections.min"
    ]
}

//@Configuration
public class ShiroConfig {
      ...
}

我再次启动应用程序,我得到了所有：

{
names: [
"jvm.memory.max",
"process.files.max",
"jvm.gc.memory.promoted",
"tomcat.cache.hit",
"system.load.average.1m",
"tomcat.cache.access",
"jvm.memory.used",
"jvm.gc.max.data.size",
"jdbc.connections.max",
"jdbc.connections.min",
"jvm.gc.pause",
"jvm.memory.committed",
"system.cpu.count",
"logback.events",
"tomcat.global.sent",
"jvm.buffer.memory.used",
"tomcat.sessions.created",
"jvm.threads.daemon",
"system.cpu.usage",
"jvm.gc.memory.allocated",
"tomcat.global.request.max",
"tomcat.global.request",
"tomcat.sessions.expired",
"jvm.threads.live",
"jvm.threads.peak",
"tomcat.global.received",
"process.uptime",
"tomcat.sessions.rejected",
"process.cpu.usage",
"tomcat.threads.config.max",
"jvm.classes.loaded",
"jvm.classes.unloaded",
"tomcat.global.error",
"tomcat.sessions.active.current",
"tomcat.sessions.alive.max",
"jvm.gc.live.data.size",
"tomcat.servlet.request.max",
"tomcat.threads.current",
"tomcat.servlet.request",
"process.files.open",
"jvm.buffer.count",
"jvm.buffer.total.capacity",
"tomcat.sessions.active.max",
"tomcat.threads.busy",
"process.start.time",
"tomcat.servlet.error"
]
}

我想同时使用执行器和四郎。谢谢你的帮助。

Answer 1

正如我所预料的，这个问题是由bean的加载顺序引起的。

我在项目中使用了四郎。

Shiro的验证方法使用MyBatis从数据库中读取数据。

public class SpringContextUtil implements ApplicationContextAware {

    private static ApplicationContext applicationContext;

    public void setApplicationContext(ApplicationContext applicationContext)
            throws BeansException {
        SpringContextUtil.applicationContext = applicationContext;
    }

    public static ApplicationContext getApplicationContext() {
        return applicationContext;
    }

    public static Object getBean(String beanId) throws BeansException {
        return applicationContext.getBean(beanId);
    }
}

然后

StoreMapper userMapper = (UserMapper) SpringContextUtil.getBean("userMapper");
UserModel userModel = userMapper.findUserByName(name);

问题暂时可以解决。这只是权宜之计，但此刻我没有更好的办法。
