  • spring.datasource.url怎么写 spring.datasource.name 和spring.datasource.username 千次阅读
    2021-06-15 05:13:05

    spring.datasource.name 和spring.datasource.username

    所踩的坑
    spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
    spring.datasource.url=jdbc:mysql://localhost:3306/thread?useSSL=false&useUnicode=true&characterEncoding=UTF-8
    spring.datasource.username=root
    spring.datasource.password=ying.115

    以上的是正确的用法
    而这个却不知道有什么当你用idea的时候。用提示里给的选择会有这个。
    我也看过源码却实不知里面的作用。这个让我也很头痛。也让我踩了一个大坑所以我记录一下
    spring.datasource.name=

    原因

    由于 Git 的分支切换问题，导致需要重新导入 JDK ，而且， IDEA 没有自动识别当前项目为 Maven 管理的项目，所以需要重新导入一下。

    解决办法

    看一下自己是不是 Maven 项目，点击 IDEA 下图中的1，然后看一下3有没有，如果没有，可以分别点一下2的两个按钮，看有了没有：
    在这里插入图片描述
    如果没有的话，你可以去 pom.xml 文件里，右击，看能够重新引入依赖，如果没有相应的按钮，你会看到提示添加此项目为Maven项目的按钮，点击就可以了。

    当然，如果你还不是这种情况的话，你可以尝试一下： clean 并重新编译一下项目，记住这个思路就没错了。

    参考：http://120.203.18.89:6969/41/could-not-resolve-placeholder-spring-datasource-url-in-value-spring-datasource-url/

    今天在测试环境运行Maven工程时，出现莫名其妙的无法初始化mybatis错误，主要是读取不到配置文件里面，关于数据库的配置。

    工程有多个profile，在Idea里面设置了运行时的配置文件，但是运行时没有生效。

    最后通过修改Maven解决，不用自带的Maven。

    今天使用spring boot配置两个数据源，出现了问题。

    使用数据源配置

    app.dataource.url=jdbc:mysql://localhost/test
app.datasource.username=dbuser
app.datasource.password=dbpass
app.datasource.driverClassName=com.mysql.cj.jdbc.Driver提示我：jdbcUrl is required with driverClassName。

    上网搜了一下，结果是使用app.datasource.url的锅。

    spring.datasource.url 数据库的 JDBC URL。

    spring.datasource.jdbc-url 用来创建连接的 JDBC URL。

    官方文档的解释是：

    因为连接池的实际类型没有被公开，所以在您的自定义数据源的元数据中没有生成密钥，而且在IDE中没有完成(因为DataSource接口没有暴露属性)。另外，如果您碰巧在类路径上有Hikari，那么这个基本设置就不起作用了，因为Hikari没有url属性(但是确实有一个jdbcUrl属性)。在这种情况下，您必须重写您的配置如下:

    app.datasource.jdbc-url=jdbc:mysql://localhost/test
app.datasource.username=dbuser
app.datasource.password=dbpass
