【中文标题】Spring Boot autoconfig 仍在使用 Tomcat 数据源而不是 HikariCP?【英文标题】:Spring Boot autoconfig is still taking Tomcat Datasource instead HikariCP? 【发布时间】:2015-12-10 20:55:40 【问题描述】:

我有我的 Spring Boot 1.2.5.RELEASE 服务,我想使用 HikariCP 数据源而不是默认的 tomcat-jdbc。所以,根据这个Spring Boot Reference,我知道我只需要从类路径中排除tomcat-jdbc并添加HikariCP

这是我的 pom.xml:

所以,HikariCP 肯定在类路径中,而tomcat-jdbc 不在。但是当我启动服务时,autoconfig 仍在创建 org.apache.tomcat.jdbc.pool.DataSource 而不是 HikariCP 一个。

我做错了什么?


编辑

这是我的应用程序启动器:

@SpringBootApplication
@EnableHypermediaSupport(type = HypermediaType.HAL)
public class ApplicationRunner 

    public static void main(String[] args) 
        SpringApplication.run(ApplicationRunner.class, args);
    


【问题讨论】:

你是如何启动服务的? 尝试清理项目,也许 jar 仍然在您的工件的输出中。 您是从命令行运行 jar 还是从 IDE 启动主类。 (如果后者你能提到你的IDE)至少尝试从命令行运行jar。 你能验证你的类路径上没有这个类org.apache.tomcat.jdbc.pool.DataSource,在eclipse上打开类型(ctrl+shif+t)类型DataSource,这个类org.apache.tomcat.jdbc.pool.DataSource是否出现在列表中? 先尝试最简单的。尝试清理您的项目以确保不存在 tomcat jar。此外,您确定您没有在 XML 中定义任何可能潜入您的类路径的上下文吗? 【参考方案1】: 在你的 pom 中包含 Hikari

将以下属性添加到您的 application.yml

spring:
  datasource:
    type: com.zaxxer.hikari.HikariDataSource
    ...

【讨论】:

【参考方案2】:

编辑:这个答案提供了在标准 Spring 中配置 Hikari 的方法,对 Boot 也有效。但是,自从我编写 Boot 以来,它已经为 Hikari 添加了更大的集成,因此像 this 这样的答案可能是有效的并且更适合 Boot。

只需在 @Configuration 类中提供数据源:

@Configuration
public class HikariCPConfig 

    @Value("$hikari.driverclassname")
    private String driverClassName;

    @Value("$hikari.jdbc.url")
    private String jdbcUrl;

    @Value("$hikari.username")
    private String userName;

    @Value("$hikari.password")
    private String password;

    @Value("$hikari.pool.size")
    private int poolSize;

    @Bean(destroyMethod = "close")
    public DataSource dataSource() 
        final HikariDataSource ds = new HikariDataSource();
        ds.setMaximumPoolSize(poolSize);
        ds.setDriverClassName(driverClassName);
        ds.setJdbcUrl(jdbcUrl);
        ds.setUsername(userName);
        ds.setPassword(password);
        return ds;
    


然后,在 application.properties 文件中,声明数据源的属性,这些属性可以由 maven 构建提供:

#Hikari
hikari.driverclassname = com.mysql.jdbc.Driver
hikari.jdbc.url = jdbc:mysql://localhost:3306/my_db
hikari.username = $db.username
hikari.password = $db.password
hikari.pool.size = 5

然后你需要 Spring 来扫描你的 HikariCPConfig 类,但是当你使用 @SpringBootApplication 时,它等同于 @Configuration @EnableAutoConfiguration@ComponentScan 它应该不是问题。

【讨论】:

由于这是一个有效的解决方案,我试图避免这种方式来利用 Spring Boot 自动配置。但如果问题仍然存在,我肯定会这样做。谢谢! 我知道,但是 tomcat 连接在 prod 中失败,因为它会在一段时间不活动时关闭。我认为 hikaricp 可能不会发生这种情况(或者我必须为每个请求设置测试连接,这会大大降低性能) 我解决了这个问题,(但我不知道实际上如何:P)。只是出于另一个原因重新安装了eclipse,一切正常。谢谢!接受你的回答,因为无论如何这是一个解决方案 这听起来可能有点陈词滥调,但我什至不知道发生了什么……我刚刚重新安装了 eclipse(出于其他原因),它就可以工作了……这是一个eclipse-cache 相关问题可能吗?这很奇怪,因为我尝试清理项目并更新依赖项但没有成功。无论如何,我明天会尝试重现错误,看看会发生什么:-) @jscherman,我最近遇到了与 Tomcat 连接池相同的问题(它在一段时间后被关闭,仅在生产中)。我用这个配置解决了这个问题:spring.datasource.test-on-borrow: truespring.datasource.validation-query: SELECT 1。这样你就可以强制池验证每个连接。【参考方案3】:

spring.datasouce.type 以 spring boot 1.3.0 开头,所以在 1.2.5 上不起作用

【讨论】:

什么意思?我在哪里使用 spring.datasource.type? 如果你使用的是1.3.0+,你可以指定属性spring.datasouce.type,否则你必须定义一个bean来覆盖spring-boot自动配置。 我认为您的评论是对@Ben 评论的回应。我明白你所说的,但是当我提出这个问题时,正如你所说,我不能使用 datasour r 类型参数。这样做的方法是我说提到的文档:从类路径中获取 hikari。问题是它也不起作用。然后重新安装eclipse后问题就奇怪了,所以我不知道是什么问题 如果你把war部署到tomcat的webapps目录下。 tomcat-jdbc lib 已经存在。 spring-boot 将在 hikaricp 之前搜索 tomcat-jdbc。所以你的配置将不起作用。我写了一个样本。 github.com/zhanhb/spring-boot-druid-sample/blob/…
