किसी कारण से वहाँ दो groupfor querydsl हैं:

यहाँ मेरी pom.xml फ़ाइल है: यहाँ सवाल में जावा वर्ग है। एक com.querydsl है, दूसरा com.mysema.querydsl है। ऐसा लगता है कि वसंत पहले के साथ काम करता है, जबकि आप दूसरे का उपयोग करते हैं। आप पाते हैं कि वसंत com.querydsl की आवश्यकता है। कोर .types.Predicate, लेकिन com.mysema.querydsl संस्करण में पैकेज नाम com.mysema है। क्वेरी .types.Predicate।

लंबी कहानी लघु वसंत com.querydsl की आवश्यकता है। विन्यास कि मेरे लिए काम किया था:

Answer 2

मैं इस समस्या थी। आप इसे हल करने के लिए this दस्तावेज़ का उपयोग कर सकते हैं।

इस दस्तावेज़ के अनुसार हम निर्भरता नीचे का उपयोग करें और

 <dependency> 
      <groupId>com.querydsl</groupId> 
      <artifactId>querydsl-apt</artifactId> 
      <version>4.1.3</version> 
      <scope>provided</scope> 
     </dependency> 
     <dependency> 
      <groupId>com.querydsl</groupId> 
      <artifactId>querydsl-jpa</artifactId> 
      <version>4.1.3</version> 
     </dependency> 
     <dependency> 
      <groupId>org.slf4j</groupId> 
      <artifactId>slf4j-log4j12</artifactId> 
      <version>1.6.1</version> 
     </dependency> 

और

  <plugin> 
       <groupId>com.mysema.maven</groupId> 
       <artifactId>apt-maven-plugin</artifactId> 
       <version>1.1.3</version> 
       <executions> 
        <execution> 
         <goals> 
          <goal>process</goal> 
         </goals> 
         <configuration> 
          <outputDirectory>target/generated-sources/java</outputDirectory> 
          <processor>com.querydsl.apt.jpa.JPAAnnotationProcessor</processor> 
         </configuration> 
        </execution> 
       </executions> 
      </plugin> 

प्लग और अनुकूलित विधि ओवरराइड करने के लिए हो सकता है। यह उस मामले के लिए एक उदाहरण भंडार है।

public interface UserRepository extends PagingAndSortingRepository<User, Long>,QueryDslPredicateExecutor<User>,QuerydslBinderCustomizer<QUser> { 


    @Override 
    default public void customize(QuerydslBindings bindings, QUser root) { 
     bindings.bind(String.class).first(
      (StringPath path, String value) -> path.containsIgnoreCase(value)); 
     bindings.excluding(root.email); 
    } 
}
