将 DataSource 配置迁移到属性文件答案

【问题标题】：Migrate DataSource configuration to properties file将 DataSource 配置迁移到属性文件

【问题描述】：

我正在尝试将 DataSource 配置迁移到 Spring Boot 属性文件（我们最近将旧 Spring 应用程序迁移到 Spring Boot），但是在定义所有必需的属性时遇到问题。我试图关注所有documentation，但显然我仍然缺少一些东西。

这是 @Configuration 文件中的初始 DataSource 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 定义并尝试将其替换为以下属性：

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遇到以下异常：

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

有人可以指出我在这里缺少什么吗？

【问题讨论】：

代替spring.datasource.dialect，尝试使用spring.jpa.database-platform。
@BrunoCésar 不幸的是，这也不起作用
另一种方法是设置休眠属性，如下所示：spring.jpa.properties.hibernate.dialect。查看我的配置，我没有设置方言，因为它是从连接中查找的。span>
无论我是否指定方言，我都会收到此异常，因此我认为我一定是做错了。一切都与以前的 bean 定义一起工作，所以我确信我的应用程序的所有其他部分都很好，这与迁移到属性有关
我不知道你的配置到底如何，所以这里很难重现，因为 spring boot 有很多配置方法。特别是我使用datasource.* 而不是spring.datasource.*，这与引导1.4.0。在另一种情况下，对于启动 1.4.2，我使用spring.datasource.*，但使用type 而不是driver-class-name 或dialect 和spring.jpa.database-platform 方言。也许这对你有帮助：docs.spring.io/spring-boot/docs/current/reference/html/…

【解决方案1】：

试试这个设置：

## 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

您必须将此文件添加到资源文件夹中，名称为 application.properties。

【讨论】：

这与我的问题几乎相同。我不需要密码和用户名，因为我不将它们用于我现在正在测试的本地内存设置。无论如何，它仍然会产生 seame 异常
请添加主类。
