需要配置 exclude = \{DataSourceAutoConfiguration.class\})

@SpringBootApplication(scanBasePackages = {"com.quickapp"}, exclude = {DataSourceAutoConfiguration.class})
    @EnableTransactionManagement(proxyTargetClass = true)
    @EnableWebMvc
    @MapperScan("com.quickapp.mapper")
    public class Application {
    
    }

多数据源配置

@SpringBootApplication(scanBasePackages = {"com..quickapp"}, exclude = {DataSourceAutoConfiguration.class})
    @EnableTransactionManagement(proxyTargetClass = true)
    @EnableWebMvc
    @MapperScan("com.xiaomi.mina.quickapp.mapper")
    public class Application {
        public static void main(String[] args) {
            SpringApplication.run(Application.class, args);
        }
    
        @Bean(name = "datasource1")
        @ConfigurationProperties(prefix = "spring.datasource")
        public DruidDataSource dataSource1() {
            return new DruidDataSource();
        }
    
        @Bean(name = "datasource2")
        @ConfigurationProperties(prefix = "spring.datasource2")
        public DruidDataSource dataSource2() {
            return new DruidDataSource();
        }
    
        /**

        @Primary
        @Bean
        public DataSource dynamicDataSource() {
            DynamicDataSource dynamicDataSource = new DynamicDataSource();
            // 默认数据源
            dynamicDataSource.setDefaultTargetDataSource(dataSource1());
            // 配置多数据源
            Map<Object, Object> dsMap = new HashMap();
            dsMap.put("datasource1", dataSource1());
            dsMap.put("datasource2", dataSource2());
    
            dynamicDataSource.setTargetDataSources(dsMap);
            return dynamicDataSource;
        }
    
        @Bean
        public SqlSessionFactory sqlSessionFactoryBean() throws Exception {
    
            SqlSessionFactoryBean sqlSessionFactoryBean = new SqlSessionFactoryBean();
            sqlSessionFactoryBean.setDataSource(dynamicDataSource());
            PathMatchingResourcePatternResolver resolver = new PathMatchingResourcePatternResolver();
            sqlSessionFactoryBean.setPlugins(new Interceptor[]{new RouterInterceptor()});
            sqlSessionFactoryBean.setMapperLocations(resolver
                    .getResources("classpath:/com/quickapp/mapper/*.xml"));
    
            return sqlSessionFactoryBean.getObject();
        }
