即使数据库已关闭，如何使 Spring 服务器启动?
我正在使用 Spring Boot(1.4.7) &MyBatis.
I'm using a Spring Boot(1.4.7) & MyBatis.
spring.main1.datasource.url=jdbc:mariadb://192.168.0.11:3306/testdb?useUnicode=true&characterEncoding=utf8&autoReconnect=true&socketTimeout=5000&connectTimeout=3000
spring.main1.datasource.username=username
spring.main1.datasource.password=password
spring.main1.datasource.driverClassName=org.mariadb.jdbc.Driver
spring.main1.datasource.tomcat.test-on-borrow=true
spring.main1.datasource.tomcat.test-while-idle=true
spring.main1.datasource.tomcat.validation-query=SELECT 1
spring.main1.datasource.tomcat.validation-query-timeout=5000
spring.main1.datasource.tomcat.validation-interval=5000
spring.main1.datasource.tomcat.max-wait=5000
spring.main1.datasource.continue-on-error=true
当 Eclipse 或 Linux 服务器上的数据库断开连接时，我无法启动程序并出现错误.(数据库不在本地主机上.)
I cannot start program with errors when database is disconnected on Eclipse or Linux server. (Database is not located on localhost.)
当我尝试使用断开连接的数据库启动程序时，打印这个.
When I try to start program with disconnected database, print this.
java.sql.SQLNonTransientConnectionException: Could not connect to address=(host=192.168.0.11)(port=3306)(type=master) : connect timed out
Cause: org.springframework.jdbc.CannotGetJdbcConnectionException: Could not get JDBC Connection; nested exception is java.sql.SQLNonTransientConnectionException: Could not connect to address=(host=192.168.0.11)(port=3306)(type=master) : connect timed out
Stopping service [Tomcat]
Application startup failed
有什么办法吗?
谢谢
推荐答案
你可以设置:
spring.sql.init.continue-on-error=true
在您的 application.properties 中.
in your application.properties.
根据 Spring Boot 2.5.5 用户指南:
默认情况下，Spring Boot 启用其基于脚本的数据库初始化程序的快速失败功能.这意味着，如果脚本导致异常，应用程序将无法启动.您可以通过设置 spring.sql.init.continue-on-error 来调整该行为.
By default, Spring Boot enables the fail-fast feature of its script-based database initializer. This means that, if the scripts cause exceptions, the application fails to start. You can tune that behavior by setting
spring.sql.init.continue-on-error.
P.S.:在 Spring Boot 2.5 之前，该属性被命名为 spring.datasource.continue-on-error.
P.S.: Before Spring Boot 2.5, the property was named spring.datasource.continue-on-error.
