应用

自带的路径

localhost:8080/mycommunity/actuator/health

自定义路径

@Component
@Endpoint(id = "database")
public class DatabaseEndpoint {

    private static final Logger logger = LoggerFactory.getLogger(DatabaseEndpoint.class);

    @Autowired
    private DataSource dataSource;

    // readOperation means this method can only be accessed by get request
    // writeOperation means this method can only be accessed by post request
    @ReadOperation
    public String checkConnection(){
        try(
                Connection connection = dataSource.getConnection();
           ) {
            return CommunityUtil.getJSONString(0,"success");
        } catch (SQLException e) {
            e.printStackTrace();
            logger.error("failed");
        }
        return CommunityUtil.getJSONString(1, "failed");
    }
}

访问浏览器：localhost:8080/mycommunity/actuator/database

注意actuator路径只能对管理员访问，注意做权限管理
