无法在 Spring Boot 1.4 中设置 spring.datasource.type [英] Not able to set spring.datasource.type in spring boot 1.4

问题描述

问题是无法设置 spring.datasource.type"，

The question is " Not able to set spring.datasource.type " ,

在 spring boot 1.3 中可以工作，但在 spring boot 1.4 中不能工作，不知道为什么?

In spring boot 1.3 can work , but in spring boot 1.4 can't work , I don't know why ?

以下是我的 application.properties:

The following is my application.properties:

spring.datasource.type= com.alibaba.druid.pool.DruidDataSource
spring.datasource.url = jdbc:mysql://localhost:3306/api-2016
spring.datasource.username = root
spring.datasource.password = root
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.max-active=20
spring.datasource.max-idle=8
spring.datasource.min-idle=8
spring.datasource.initial-size=10

谁能告诉我为什么?

推荐答案

从 Spring Boot 1.4 开始，我们不再将 DataSource 实例映射到 spring.datasource 所以所有未应用自定义(max-active 等).

As of Spring Boot 1.4, we no longer map the DataSource instance to spring.datasource so all the customizations (max-active, etc) aren't applied.

请阅读发布注释.DruidDataSource 上的自定义从未被支持，这是一个副作用.您可以通过创建自己的数据源 bean 来恢复该行为:

Please read the release notes. The customizations on DruidDataSource were never supported and this was working as a side effect. You can restore that behaviour by creating your own datasource bean:

@Bean
@ConfigurationProprties("app.datasource.druid")
public DataSource dataSource() { ... }

并将您特定于德鲁伊的设置更改为 app.datasource.druid.如果您启用 注解处理器 您将在 IDE 中获得这些密钥的内容帮助！

And change your druid-specific settings to app.datasource.druid. If you enable the annotation processor you'll get content assistance in your IDE for those keys!

说完并查看代码后，我现在意识到我们有效地破坏了 spring.datasource.type 所以我创建了 #6695 跟踪该问题.

Having said that and poking at the code, I realize now that we effectively broke spring.datasource.type so I've created #6695 to track that issue.
