Question

您好我有以下查询，但是Spring数据solr为最后一个参数放入参数1值而不是param 10值：“AND days_ss :(？10）”......我猜它看到了？1而不是？ 10

无论如何，我尝试使用：像JPA一样的日子，但这会干扰lucene语法

    @Highlight(prefix = "<b>", postfix = "</b>")
    @Query("""text:(?0) AND moduleLevel_s:(?1) AND programOfStudy_s:\"?2\" AND yearOfEntry_i:?3 AND yearOfStudy_i:?4 AND unitValue_d:?5 AND
department_s:(?6) AND teachers_ss:(?7) AND cappedAccess_b:?8 AND terms_ss:(?9) AND days_ss:(?10)""")
    HighlightPage<CourseGuide> advancedSearch(@Param(value = "query") List<String> query,
                                     @Param(value = "moduleLevel") List<ModuleLevel> moduleLevel,
                                     @Param(value = "programOfStudy") String programOfStudy,
                                     @Param(value = "yearOfEntry") def yearOfEntry,
                                     @Param(value = "yearOfStudy") def yearOfStudy,
                                     @Param(value = "unitValue") def unitValue,
                                     @Param(value = "department") List<String> department,
                                     @Param(value = "teachers") List<String> teachers,
                                     @Param(value = "cappedAccess") def cappedAccess,
                                     @Param(value = "terms") List<String> terms,
                                     @Param(value = "days") List<String> days,Pageable pageable)

实际上发生的事情是，在它的param替换过程中，它在字符串中查找所有出现的“？1”并错误地弄乱了我的？10占位符。如果它在另一个方向上工作，事情可能会好起来，即先处理？10然后？9，然后是？8等等

我有同样的问题。我在Spring-data-solr上为这个问题创建了一个Jira，https://jira.spring.io/browse/DATASOLR-296?jql=text%20~%20%22%40Query%22%20ORDER%20BY%20created%20DESC

但我找到了解决方案。

您需要使用solrTemplate。

例如：

在你的solrConfiguration.java

中

@Configuration
@EnableSolrRepositories(value = "com.project.repository.solr",     multicoreSupport = true)
public class SolrConfiguration implements EnvironmentAware{

    private RelaxedPropertyResolver propertyResolver;
    private Environment             environment;

    @Override
    public void setEnvironment(Environment environment) {
        this.environment = environment;
        this.propertyResolver = new RelaxedPropertyResolver(environment, "spring.data.solr.");
    }

    @Bean
    public SolrServer solrServer() {
        String solrHost = propertyResolver.getProperty("host");
        return new HttpSolrServer(solrHost);
    }

    @Bean(name = "testSolrTemplate")
    public SolrOperations testSolrTemplate() {
        HttpSolrServer httpSolrServer = new HttpSolrServer(propertyResolver.getProperty("host"));
        return new SolrTemplate(httpSolrServer, "TestCore");
    }
}

然后在你的TestRepository.java

中

public interface TestRepository extends TestRepositoryCustom, SolrRepository<Test, String>, SolrCrudRepository<Test, String> {
}

然后在你的TestRepositoryCustom.java

中

interface TestRepositoryCustom {
    public ArrayList<Test> findTests(
        String arg1, String arg2, String arg3, String arg4, String arg5, String arg6, String arg7, String arg8, String arg9, String arg10, String arg11
    );
}

然后在你的TestRepositoryImpl.java

中

public class TestRepositoryImpl implements TestRepositoryCustom {
    @Resource
    private SolrTemplate testSolrTemplate;

    @Override
    public ArrayList<Test> findTests(
        String arg1, String arg2, String arg3, String arg4, String arg5, String arg6, String arg7, String arg8, String arg9, String arg10, String arg11
    ) {
        Criteria criteria = new Criteria(Criteria.WILDCARD).expression(Criteria.WILDCARD)
                .and(new Criteria("arg1").expression(arg1))
                .and(new Criteria("arg2").expression(arg2))
                .and(new Criteria("arg3").expression(arg3))
                .and(new Criteria("arg4").expression(arg4))
                .and(new Criteria("arg5").expression(arg5))
                .and(new Criteria("arg6").expression(arg6))
                .and(new Criteria("arg7").expression(arg7))
                .and(new Criteria("arg8").expression(arg8))
                .and(new Criteria("arg9").expression(arg9))
                .and(new Criteria("arg10").expression(arg10))
                .and(new Criteria("arg11").expression(arg11))
        ;

        return new ArrayList<>(testSolrTemplate.queryForPage(new SimpleQuery(criteria).setRows(2147483647), Test.class).getContent());
    }

}
