我创建了一个带有spring boot和JOOQ的简单项目，添加了依赖“spring-boot-starter-jooq”。我编译时应用程序无法启动。
这是pom.xml：

这是我想要注入DSLContext的地方：
@Service
public class GameDao {
private final DSLContext create;
@Autowired
public GameDao(DSLContext dslContext) {
this.create = dslContext;
}
}
错误信息：
上下文初始化期间遇到异常 - 取消刷新尝试：org.springframework.beans.factory.UnsatisfiedDependencyException：创建文件中定义名为'gameDao'的bean时出错[/ Users / yangzhiwei / Downloads / BingoApi / target / classes / com / bingo / api /dao/GameDao.class]：通过构造函数参数0表示的不满意的依赖;嵌套异常是org.springframework.beans.factory.NoSuchBeanDefinitionException：没有类型为'org.jooq.DSLContext'的限定bean可用：预期至少有1个bean有资格作为autowire候选者。依赖注释：{}
/***************************
应用程序未能启动
/***************************
说明：com.bingo.api.dao.GameDao中构造函数的参数0需要一个无法找到的类型为'org.jooq.DSLContext'的bean。操作：考虑在配置中定义类型为'org.jooq.DSLContext'的bean。
有什么帮助吗？
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'
你需要实例化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将为您创建JooqAutoConfiguration。
可选：添加配置以创建DSLContext bean。这是一个例子。
@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;
}
}
