连接池报错:Failed to instantiate [org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter]

场景:

search服务junit测试跑不起来,代码啥也没改过



排查:

...
Failed to instantiate [org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter]
...
dataSource or dataSourceClassName or jdbcUrl is required

org.springframework.boot.jdbc.DataSourceBuilder#build

	private static final String[] DATA_SOURCE_TYPE_NAMES = new String[] {
			"com.zaxxer.hikari.HikariDataSource",
			"org.apache.tomcat.jdbc.pool.DataSource",
			"org.apache.commons.dbcp2.BasicDataSource" };

private Map<String, String> properties = new HashMap<>();

	private void maybeGetDriverClassName() {
		if (!this.properties.containsKey("driverClassName")
				&& this.properties.containsKey("url")) {
			String url = this.properties.get("url");
			String driverClass = DatabaseDriver.fromJdbcUrl(url).getDriverClassName();
			this.properties.put("driverClassName", driverClass);
		}
	}

发现其properties hashMap 没有内容

即配置在application.properties中的内容未生效



原因及解决:

在IDEA中查看module,发现有两个module

一个是xxxx-elasticsearch-service,另一个是com.xxxx.xxxx.esearch.xxxx-elasticsearch-service

原来gradle中配置了

group = 'com.xxxx.xxxx.esearch'
version = '0.0.1-SNAPSHOT'

将group注释掉,重新导入project,就可以正常测试了

怀疑这些都是IDEA自身的问题,当打包之后,其classes中文件夹的格式仍旧是com/xxxx/xxxx/esearch
