Question

我在JHipster中的JOOQ配置有问题。我正在尝试在我的测试应用程序中使用petrikainulainen.net配置，但是当我编译时，我有很多错误。我正在使用jooq-jhipster-generator。

我不知道我做错了什么。

Answer 1

您不希望所有这些DataSource都是bean。如果您阅读异常并查看那些DataSource装饰器的Java文档，它将告诉您不要创建除最外层bean之外的bean。

所以诀窍是从除@Bean外的所有内容中移除DataSource。

//remove @Bean
public DataSource source(){

    BoneCPDataSource ds = new BoneCPDataSource();
    ds.setDriverClass("org.postgresql.ds.PGSimpleDataSource");
    ds.setJdbcUrl("jdbc:postgresql://localhost:5432/test");
    ds.setUsername("user");
    ds.setPassword("password");

    return ds;
}

 @Bean
public DefaultConfiguration configuration(){
    DefaultConfiguration jooqConfiguration = new DefaultConfiguration();

    jooqConfiguration.set(connectionProvider());
    jooqConfiguration.set(new DefaultExecuteListenerProvider(jooqToSpringExceptionTransformer()));

    SQLDialect dialect = SQLDialect.valueOf(String.valueOf(SQLDialect.POSTGRES));
    jooqConfiguration.set(dialect);

    return jooqConfiguration;
}

//remove @Bean
public LazyConnectionDataSourceProxy lazyConnectionDataSource() {

    return new LazyConnectionDataSourceProxy(source());
}

@Bean
public TransactionAwareDataSourceProxy transactionAwareDataSource() {
    return new TransactionAwareDataSourceProxy(lazyConnectionDataSource());
}

@Bean
public DataSourceTransactionManager transactionManager() {
    return new DataSourceTransactionManager(transactionAwareDataSource());
}

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

@Bean
public JOOQToSpringExceptionTransformer jooqToSpringExceptionTransformer() {
    return new JOOQToSpringExceptionTransformer();
}

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

你可能甚至不需要LazyConnectionDataSourceProxy，因为我相信BoneCP可以做到这一点。

Answer 2

错误消息很明确：您已经定义了4个datasource类型的bean。 userRepository需要一个数据源，因此Spring不知道要注入哪个数据源。

没有定义[javax.sql.DataSource]类型的限定bean：预期单匹配bean但发现4： transactionAwareDataSource，来源，lazyConnectionDataSource，数据源

从我看到你将所有这些都暴露为bean，但source和lazyConnectionDataSource用于构建transactionAwareDataSource，因此不应使用@Bean注释它们。

然后有dataSource bean，它似乎是由你的应用程序属性中的spring boot创建的。

为什么在JHipster使用Hikari时使用BoneCP？
