Java 带JOOQ的Spring boot收到了一条消息；需要类型为'的bean；org.jooq.DSLContext'；“找不到”；

我用SpringBoot和JOOQ创建了一个简单的项目，添加了依赖项“SpringBootStarterJooq”。我编译时应用程序启动失败

这是pom.xml:

描述：com.bingo.api.dao.GameDao中构造函数的参数0需要找不到类型为“org.jooq.DSLContext”的bean。 动作：考虑在配置中定义一个类型为“org .joq.dSLeValice”的bean。

需要帮忙吗

更新： 1.我在application.properties文件中添加了如下属性：

spring.datasource.url==jdbc:mysql://123.123.123.123:3306/bingo
spring.datasource.user=username
spring.datasource.password=password

2.我添加了jooqConfiguration类。 现在收到另一条错误消息：

Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'jooqConfiguration': Unsatisfied dependency expressed through field 'dataSource'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'javax.sql.DataSource' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}

APPLICATION FAILED TO START

Description:

Field dataSource in com.bingo.api.config.JooqConfiguration required a bean of type 'javax.sql.DataSource' that could not be found.
    - Bean method 'dataSource' not loaded because @ConditionalOnProperty (spring.datasource.jndi-name) did not find property 'jndi-name'
    - Bean method 'dataSource' not loaded because @ConditionalOnClass did not find required class 'javax.transaction.TransactionManager'

您需要实例化

DSLContext

首先添加属性：

spring.datasource.url=jdbc:h2:~/jooq
spring.datasource.username=sa
spring.datasource.password=xxx

编辑：根据jhyot的评论。。。添加配置应该足够好，因为

DSLContext

将通过

JooqAutoConfiguration

为您创建

可选：添加配置以创建DSLContextbean。这里有一个例子

@Configuration
public class JooqConfiguration {

    @Autowired
    private DataSource dataSource;

    @Bean
    public DataSourceConnectionProvider connectionProvider() {
        return new DataSourceConnectionProvider
          (new TransactionAwareDataSourceProxy(dataSource));
    }

    @Bean
    public DefaultDSLContext dsl() {
        return new DefaultDSLContext(configuration());
    }

    public DefaultConfiguration configuration() {
        DefaultConfiguration jooqConfiguration = new DefaultConfiguration();
        jooqConfiguration.set(connectionProvider());
        jooqConfiguration
          .set(new DefaultExecuteListenerProvider(exceptionTransformer()));

        return jooqConfiguration;
    }

}

参考：

实际上，您不需要创建DSLContext实例并自行配置。弹簧靴可以帮你。看看JooqAutoConfiguration.java。但是，在Spring Boot加载DSLContext之前，您可能确实需要提供DB配置并在类路径上安装DB驱动程序。@jhyot是的，您是对的。我更新了我的答案。谢谢你谢谢你的帮助。我添加了属性和jooqConfiguration类，但收到另一条错误消息。我更新了问题。您是否遵循了我提供的链接中的步骤4？@JoseMartinez我重新安装了JDK，然后问题得到了解决。其实不知道原因。谢谢。spring.datasource的配置应该足够了。您有一个额外的

登录

spring.datasource.url

。
