JavaMelody與Spring Boot和Hikari DataSource

Question

我在springboot projet中安裝javamelody（根據本教程：https://github.com/javamelody/javamelody/wiki/SpringBootStarter：安裝時沒有使用spring-boot-starter），但在runnig服務器時。

在application.yml文件中，我添加了 aop： proxy-target-class：true 但仍無法正常工作。

請幫忙。 我得到這個錯誤：

APPLICATION FAILED TO START 

Description: 

The bean 'dataSource' could not be injected as a 'com.zaxxer.hikari.HikariDataSource' because it is a JDK dynamic proxy that implements: 
javax.sql.DataSource 
java.io.Closeable 

Action: 

Consider injecting the bean as one of its interfaces or forcing the use of CGLib-based proxies by setting proxyTargetClass=true on @enableasync and/or @enablecaching."

我有同樣的問題。什麼工作對我來說是手動定義HikariDataSource豆，所以你做不需要設置proxy-target-class=true：

@Bean 
@ConfigurationProperties(prefix = "spring.datasource") 
public HikariDataSource dataSource() { 
    return (HikariDataSource) DataSourceBuilder.create().type(HikariDataSource.class).build(); 
} 

然後在application.yml更改屬性url到jdbc-url。 我還增加了javaMelody以下配置：

javamelody: 
    enabled: true 
    spring-monitoring-enabled: true 
    init-parameters: 
    log: true 
    authorized-users: admin:******** 

現在，javaMelody工作和Spring引導應用可以正常啓動。 依賴是"net.bull.javamelody:javamelody-spring-boot-starter:1.68.1"

提示：如果你的單元測試添加javaMelody破後，就完全禁用它通過應用程序配置文件的單元測試。
