Question

当尝试使用 Spring Boot 2.0.2 RELEASE 自动连接 DataSource 时，会出现以下错误，并且无法进行注入：

'无法自动接线。 “ DataSource”类型的bean不止一个。

在DataSourceConfiguration类中为HikariDataSource，BasicDataSource和Tomcat创建bean。

是否有一种方法可以使其中一个合格，并避免创建其余的一个？

@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    public SecurityConfig() {
        this.usersByUsernameQuery = // definitions here
        this.authoritiesByUsernameQuery = //
        this.allowedAuthorities = //
    }

@Autowired
    public void configureGlobal(final AuthenticationManagerBuilder auth, final DataSource dataSource) throws Exception {
        auth.jdbcAuthentication()
            .dataSource(dataSource)
            .usersByUsernameQuery(usersByUsernameQuery)
            .authoritiesByUsernameQuery(authoritiesByUsernameQuery);
    }
}

pom.xml：

application.properties：

spring.datasource.url=jdbc:mysql://localhost:9400/test
spring.datasource.username=root
spring.datasource.password=test
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
