问题


I have a problem. I'm using Spring4 and i want to add a configuration to be able to use spring data couchbase and i have an error :

org.springframework.beans.factory.BeanDefinitionStoreException: Failed to read candidate component class: file [/home/charlie/Desktop/Ultimate Projects/novare_dashboard/novare-project-dashboard/target/classes/hk/com/novare/dashboard/configuration/CouchbaseConfig.class]; nested exception is java.lang.annotation.AnnotationFormatError: Invalid default: public abstract java.lang.Class org.springframework.data.couchbase.repository.config.EnableCouchbaseRepositories.repositoryBaseClass() at org.springframework.context.annotation.ClassPathScanningCandidateComponentProvider.findCandidateComponents(ClassPathScanningCandidateComponentProvider.java:303)

Here is my code:

CouchbaseConfig.java

@Configuration
@EnableCouchbaseRepositories
public class CouchbaseConfig extends AbstractCouchbaseConfiguration{

@Override
protected List<String> bootstrapHosts() {
    return Collections.singletonList("localhost");
}

@Override
protected String getBucketName() {
    return "crud";
}

@Override
protected String getBucketPassword() {
    return "password";
}}

WebMvcConfig.java

@Configuration
@EnableWebMvc
@ComponentScan(basePackageClasses = Application.class)
public class WebMvcConfig extends WebMvcConfigurerAdapter {

@Override
public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer) {
    configurer.enable();
}

@Bean
public InternalResourceViewResolver jspViewResolver() {
    InternalResourceViewResolver bean = new InternalResourceViewResolver();
    bean.setPrefix("/WEB-INF/views/");
    bean.setSuffix(".jsp");
    return bean;
}

@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
    registry.addResourceHandler("/static/**").addResourceLocations("/WEB-INF/static/");
}}

回答1:


Can see the error for missing repositoryBaseClass config which is needed to create the repository proxies for your CouchbaseConfig class :-

nested exception is java.lang.annotation.AnnotationFormatError: Invalid default: public abstract java.lang.Class 
org.springframework.data.couchbase.repository.config.EnableCouchbaseRepositories.repositoryBaseClass() at 

Pls specify same as parameter to @EnableCouchbaseRepositories

I just found a solution regarding my error. You must change your spring-data-couchbase version to 1.2.2 and remove the annotation @Repository to your repository.
