迁移数据源配置到属性文件

Question

我正在尝试将数据源配置迁移到Spring Boot属性文件（我们最近将旧的Spring应用程序迁移到Spring Boot），但是我在定义所有必需属性方面遇到了问题。我试图遵循所有文档，但显然仍然缺少一些文档。

这是@Configuration文件中的初始数据源定义：

@Bean
public DataSource dataSource() {
    final DataSource dataSource = new DataSource();
    dataSource.setJdbcUrl(getDataSourceURL());
    try {
        dataSource.setDriverClass(getDriverName());
    }
    catch (final PropertyVetoException e) {
        throw new IllegalArgumentException("Cannot set driverClass for datasource: ", e);
    }
    return dataSource;
}

我删除了bean的定义，并试图用以下属性替换它：

spring.datasource.url=my_url
spring.datasource.driver-class-name=org.hsqldb.jdbc.JDBCDriver
spring.jooq.sql-dialect=HSQLDB
spring.datasource.dialect=org.hibernate.dialect.HSQLDialect

但是，我在应用程序启动期间得到以下例外：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'embeddedServletContainerCustomizerBeanPostProcessor': Initialization of bean failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'metaDataSourceAdvisor': Cannot resolve reference to bean 'methodSecurityMetadataSource' while setting constructor argument; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.security.config.annotation.method.configuration.GlobalMethodSecurityConfiguration': Injection of autowired dependencies failed; nested exception is java.lang.RuntimeException: Could not postProcess org.springframework.security.access.expression.method.DefaultMethodSecurityExpressionHandler@6e599e88 of type class org.springframework.security.access.expression.method.DefaultMethodSecurityExpressionHandler

有人可以向我指出我在这里缺少什么？

Answer 1

尝试使用此设置：

## JDBC part
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3306/mydatabase
spring.datasource.username=useranme
spring.datasource.password=mypassword
spring.jpa.show-sql=true
spring.jpa.hibernate.ddl-auto=create
spring.jpa.database-platform=org.hibernate.dialect.HSQLDialect

您必须使用application.properties名称中的资源文件夹中添加此文件。
