Question

我试图在我的java spring启动应用程序中捕获java.sql.SQLException。我很清楚如何在page上做到这一点。但由于我使用的是spring boot，因此我的凭据位于application.properties文件中。

我的application.properties到此：

spring.datasource.url = jdbc:oracle:thin:@//SomePathURI
spring.datasource.username= someUser
spring.datasource.password= somepass

错误输出

2017-04-04 10:18:13.866 ERROR 11684 --- [nio-8080-exec-3] o.a.c.c.C.[.[.[/].[dispatcherServlet]    : Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is org.springframework.jdbc.CannotGetJdbcConnectionException: Could not get JDBC Connection; nested exception is java.sql.SQLException: ORA-01017: invalid username/password; logon denied
] with root cause

如何捕获此异常并继续运行我的应用程序。而不是让应用程序自动停止并显示此错误？如果我的连接在application.properties中，我不明白如何尝试捕获。

Answer 1

错误很明显，您的用户名/密码错误，您需要修复它。但是，您可以设置应用程序在没有数据库连接的情况下继续，只需将以下属性添加到application.properties：

spring.datasource.continue-on-error=true

点击此处查看更多详情：https://docs.spring.io/spring-boot/docs/current/reference/html/howto-database-initialization.html#howto-initialize-a-database-using-spring-jdbc

但请注意，当您尝试使用时，需要进行验证以检查数据库连接是否正常。
