在 JHipster 中配置 JOOQ
Configuration JOOQ in JHipster
我在 JHipster 中配置 JOOQ 时遇到问题。我试图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。
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，它会告诉您除了最外层的以外不要创建 bean。
所以诀窍是从除外部 DataSource 以外的所有内容中删除 @Bean。
//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());
}
您可能甚至不需要 LazyConnectionDataSourceProxy，因为我相信 BoneCP 可以实现这种效果。
错误信息很明确：你定义了4个数据源类型的bean。 userRepository 需要一个数据源，因此 Spring 不知道要注入哪一个。
No qualifying bean of type [javax.sql.DataSource] is defined:
expected single matching bean but found 4:
transactionAwareDataSource,source,lazyConnectionDataSource,dataSource
据我所知，您将它们全部公开为 beans，但 source 和 lazyConnectionDataSource 用于构建 transactionAwareDataSource，因此不应使用 @Bean 注释它们。
然后是 dataSource bean，它似乎是由 spring 引导创建的，可能来自您的应用程序属性。
为什么 JHipster 使用 Hikari 而使用 BoneCP？
我在 JHipster 中配置 JOOQ 时遇到问题。我试图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。
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，它会告诉您除了最外层的以外不要创建 bean。
所以诀窍是从除外部 DataSource 以外的所有内容中删除 @Bean。
//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());
}
您可能甚至不需要 LazyConnectionDataSourceProxy，因为我相信 BoneCP 可以实现这种效果。
错误信息很明确：你定义了4个数据源类型的bean。 userRepository 需要一个数据源，因此 Spring 不知道要注入哪一个。
No qualifying bean of type [javax.sql.DataSource] is defined: expected single matching bean but found 4: transactionAwareDataSource,source,lazyConnectionDataSource,dataSource
据我所知，您将它们全部公开为 beans，但 source 和 lazyConnectionDataSource 用于构建 transactionAwareDataSource，因此不应使用 @Bean 注释它们。
然后是 dataSource bean，它似乎是由 spring 引导创建的，可能来自您的应用程序属性。
为什么 JHipster 使用 Hikari 而使用 BoneCP？
