Spring Boot REST:如何动态访问客户端请求中指定的适当数据库模式？

spring.datasource.url=jdbc:mysql://localhost:3306/schema1
spring.datasource.username=username1
spring.datasource.password=password1

spring.datasource.schema2.url=jdbc:mysql://localhost:3306/schema2
spring.datasource.schema2.username=username2
spring.datasource.schema2.password=password2

@Configuration
public class DataSourceConfig {

    @Primary
    @Bean
    @ConfigurationProperties(prefix = "spring.datasource")
    public DataSource dataSource() {
        return DataSourceBuilder.create().build();
    }

    @Bean(name = "schema2DataSource")
    @ConfigurationProperties(prefix = "spring.datasource.schema2")
    public DataSource schema2DataSource() {
        return DataSourceBuilder.create().build();
    }
}

@RestController
public class UserController {

    private final DataSource dataSource;

    private final DataSource schema2DataSource;

    public UserController(@Qualifier("dataSource") DataSource dataSource,
                           @Qualifier("schema2DataSource") DataSource schema2DataSource) {
        this.dataSource = dataSource;
        this.schema2DataSource = schema2DataSource;
    }

    @GetMapping("/users")
    public List<User> getUsers(@RequestParam("schema") String schema) {
        // 根据请求参数schema选择要使用的数据源
        DataSource selectedDataSource = schema.equals("schema2") ? schema2DataSource : dataSource;

        // 使用selectedDataSource执行数据库操作
        // ...

        return users;
    }
}
