将DataSource配置迁移到属性文件

Question

我试图将DataSource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），但我在定义所有必需属性时遇到了问题。我试图按照所有的documentation，但我仍然显然失去了一些东西。

这是一个@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定义，并试图具有以下属性来代替它：

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 

不过，我得到在应用程序启动期间出现以下异常：

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

Coul有人指出我在这里错过了什么？

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 

您必须添加该文件与application.properties名称的资源文件夹。
