最近在跑一个项目的时候碰到了一些问题。所以来记录一下解决方案。

1. 数据源启动就关闭 INFO com.alibaba.druid.pool.DruidDataSource- {dataSource-1} closed

解决方案：

修改 build.gradle 配置文件

//    runtime("org.apache.tomcat.embed:tomcat-embed-jasper")    compile("org.apache.tomcat.embed:tomcat-embed-jasper")

注意：这里还有一个原因，可能是由于配置文件中某一个配置缺失导致的。

多数据源未指定@Primary的问题

简述1：required a single bean, but 2 were found
简述2：At least one JAR was scanned for TLDs yet contained no TLDs. Enable debug logging for this logger for a complete list of JARs that were scanned but no TLDs were found in them. Skipping unneeded JARs during scanning can improve startup time and JSP compilation time.
要求一个单独的bean

解决方案：

@Configurationpublic class DruidConfig {    @Primary//选择一个数据源，加上@Primary注解    @ConfigurationProperties(prefix = "spring.datasource")    @Bean(initMethod = "init", destroyMethod = "close")    public DruidDataSource druidDataSource() { DruidDataSource druidDataSource = new DruidDataSource(); druidDataSource.setProxyFilters(Lists.newArrayList(statFilter())); return druidDataSource;    }    // 此处省略后面的配置}
