如果加了这个类启动就会报错，不加就可以完美运行，错误日志在下面，弄了一天了都没弄好，幸苦大哥们帮我看一看
@Configuration
public class OrderXADataSourceConfiguration {
@Bean
@ConfigurationProperties(prefix = "spring.datasource")
public DruidDataSource druidDataSource() {
return new DruidDataSource();
}
@Bean("dataSourceProxy")
public DataSource dataSource(DruidDataSource druidDataSource) {
return new DataSourceProxyXA(druidDataSource);
}
@Bean("jdbcTemplate")
public JdbcTemplate jdbcTemplate(DataSource dataSourceProxy) {
return new JdbcTemplate(dataSourceProxy);
}
}
这里是错误日志
