连接到数据库 Spring 启动时出错
Error connecting to database Spring boot
Helo 我一直在尝试使用 Spring 引导连接到数据库一段时间，但我一直收到错误消息：
java.sql.SQLException: url不能为空
我不确定我做错了什么。我试图获得这样的配置的原因是因为我想对数据库使用编码密码。

- 只需要一个数据源配置bean。我将其设置为更改活动配置文件，以便选择正确的配置。
同时创建私有变量并使用 @Value() 注释绑定它们。还将 @EnableEncryptableProperties 添加到 class.
DataConfig.java
@Configuration
@EnableEncryptableProperties
public class DataConfig {
@Value("${spring.datasource.username}")
private String userName;
@Value("${spring.datasource.password}")
private String password;
@Value("${spring.datasource.url}")
private String url;
@Value("${spring.datasource.driver-class-name}")
private String driverClassName;
@Bean
DataSource dataSource() {
return DataSourceBuilder
.create()
.username(userName)
.password(password)
.url(url)
.driverClassName(driverClassName)
.build();
}
}
就是这样，它解决了我所有的问题。

- 只需要一个数据源配置bean。我将其设置为更改活动配置文件，以便选择正确的配置。
同时创建私有变量并使用 @Value() 注释绑定它们。还将 @EnableEncryptableProperties 添加到 class.
DataConfig.java
@Configuration
@EnableEncryptableProperties
public class DataConfig {
@Value("${spring.datasource.username}")
private String userName;
@Value("${spring.datasource.password}")
private String password;
@Value("${spring.datasource.url}")
private String url;
@Value("${spring.datasource.driver-class-name}")
private String driverClassName;
@Bean
DataSource dataSource() {
return DataSourceBuilder
.create()
.username(userName)
.password(password)
.url(url)
.driverClassName(driverClassName)
.build();
}
}
就是这样，它解决了我所有的问题。
