Spring boot 应用程序未启动

Question

我的 Spring Boot 应用程序无法启动。我无法找到其根本原因。我猜 Hikari 池可能会为此造成问题。下面是日志。任何帮助将不胜感激。

Answer 1

大部分问题都可以通过调试来解决。

以下是带有调试的快速破解：

对于 Spring - 将调试点放在 SpringApplication.class 中的 CATCH 函数块中

public ConfigurableApplicationContext run(String... args) 

大多数问题将由此得知，包括：

• Bean初始化
• Spring 的无效属性

处理此类场景的理想方法是在 logback.xml 或与应用程序相关的日志文件中开始记录每个 spring 模块，该文件告诉 spring 开始记录。

如何为Spring Boot启用远程调试：

mvn spring-boot:run -Dspring-boot.run.jvmArguments="-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=5005"

或

java -Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=5005 -jar application.jar
