[英]Spring Boot with QueryDsl
I'm create a project Restful using QueryDsl and Pagination. 我使用QueryDsl和Pagination创建一个Restful项目。 This is snip my code :
这是我的代码:
Repository interface 仓库接口
@Repository
public interface PrsMainRepo extends PagingAndSortingRepository<PrsMain, String>, QuerydslPredicateExecutor<PrsMain> {
}
and 和
builder = new PrsMainPredicateBuilder();
for (SearchCriteria param : body) {
builder.with(param.getKey(), param.getOperator(), param.getValue());
}
// builder.build()=> prs_main.prs_firstname = 'Sharon'
Iterable<PrsMain> main = prsMainRepo.findAll(builder.build());
When i run my project and test with postman , i see message in eclipse and get an error : 当我运行项目并使用邮递员进行测试时,我在eclipse中看到消息并收到错误消息:
ohhiQueryTranslatorFactoryInitiator : HHH000397: Using ASTQueryTranslatorFactory
ohhiQueryTranslatorFactoryInitiator:HHH000397:使用ASTQueryTranslatorFactory
java.lang.NullPointerException
java.lang.NullPointerException
How to resolve this ? 如何解决呢? We are can show query generated when QuerydslPredicateExecutor excute ?
我们可以显示当QuerydslPredicateExecutor执行时生成的查询吗?
We are can show query generated when QuerydslPredicateExecutor excute ?
我们可以显示当QuerydslPredicateExecutor执行时生成的查询吗? For this you have to change configuration in your application configuration file.
为此,您必须在应用程序配置文件中更改配置。 There is datasource section in that configuration and you can specify inside show/hide the query.
该配置中有datasource部分,您可以在show / hide查询中指定。
