Springboot项目使用@SpringBootApplication(exclude = {DataSourceAutoConfiguration.class})失效的解决方案

Posted 2021-06-27 lovoo

前言

在微服务中，搭建的网关模块是不需要连接数据库资源的，但在公共模块mall-common中加入了druid数据库资源池，在启动application时，即使添加了(exclude = {DataSourceAutoConfiguration.class}也会报数据库连接的错误，如何彻底解决呢？

异常内容：

***************************
APPLICATION FAILED TO START
***************************

Description:

Failed to configure a DataSource: 'url' attribute is not specified and no embedded datasource could be configured.

Reason: Failed to determine a suitable driver class

解决措施1

在类上加入如下配置

/**
 * 网关启动类
 */
@EnableDiscoveryClient
@SpringBootApplication(exclude = {
        DataSourceAutoConfiguration.class,
        DataSourceTransactionManagerAutoConfiguration.class,
        DruidDataSourceAutoConfigure.class ,
        HibernateJpaAutoConfiguration.class})
public class MallGatewayApplication {

    public static void main(String[] args) {
        SpringApplication.run(MallGatewayApplication.class, args);
    }

}

解决措施2

去除下面导入

  <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>druid-spring-boot-starter</artifactId>
            <version>1.2.4</version>             
        </dependency>
