Question

J'utilise spring-data-solr (2.1.3) et solr (6.5. 1), mais quand je l'utilise solrTemplate.saveBean(Command), une exception est levée:

java.lang.NoSuchMethodError: org.apache.solr.common.SolrInputDocument: method()V not found

Ceci est mon entité

package com.catcher92.demo.solr.bean; 

import org.apache.solr.client.solrj.beans.Field; 
import java.io.Serializable; 
import java.util.List; 

/** 
* Created by catcher92 on 2017/6/7. 
*/ 
public class Command implements Serializable{ 

    @Field 
    private String id; 
    @Field 
    private String command; 
    @Field 
    private String description; 
    @Field 
    private List<String> contents; 

    public String getId() { 
     return id; 
    } 

    public void setId(String id) { 
     this.id = id; 
    } 

    public String getCommand() { 
     return command; 
    } 

    public void setCommand(String command) { 
     this.command = command; 
    } 

    public String getDescription() { 
     return description; 
    } 

    public void setDescription(String description) { 
     this.description = description; 
    } 

    public List<String> getContents() { 
     return contents; 
    } 

    public void setContents(List<String> contents) { 
     this.contents = contents; 
    } 

    @Override 
    public String toString() { 
     return "Command{" + 
       "id=" + id + 
       ", command='" + command + '\'' + 
       ", description='" + description + '\'' + 
       ", contents=" + contents + 
       '}'; 
    } 
} 

C'est ma config Solr

package com.catcher92.demo.solr.spring.config; 

import org.apache.solr.client.solrj.impl.HttpSolrClient; 
import org.springframework.context.annotation.Bean; 
import org.springframework.context.annotation.Configuration; 
import org.springframework.context.annotation.PropertySource; 
import org.springframework.core.env.Environment; 
import org.springframework.data.solr.core.SolrTemplate; 
import org.springframework.data.solr.repository.config.EnableSolrRepositories; 

import javax.annotation.Resource; 

/** 
* Created by catcher92 on 2017/6/7. 
*/ 
@Configuration 
@EnableSolrRepositories() 
@PropertySource("classpath:solr.properties") 
public class SolrConfig { 
    static final String SOLR_HOST = "solr.host"; 

    @Resource 
    private Environment environment; 

    @Bean 
    public HttpSolrClient solrClient() { 
     String solrHost = environment.getRequiredProperty(SOLR_HOST); 
     return new HttpSolrClient.Builder(solrHost).build(); 
    } 

    @Bean 
    public SolrTemplate solrTemplate() { 
     return new SolrTemplate(solrClient()); 
    } 
} 

Ceci est mon code de test

package com.catcher92.demo; 

import com.catcher92.demo.solr.bean.Command; 
import com.catcher92.demo.solr.spring.config.SpringConfig; 
import org.apache.solr.common.SolrInputDocument; 
import org.junit.Before; 
import org.junit.Test; 
import org.junit.runner.RunWith; 
import org.springframework.beans.factory.annotation.Autowired; 
import org.springframework.data.solr.core.SolrTemplate; 
import org.springframework.test.context.ContextConfiguration; 
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner; 

import java.util.Arrays; 

/** 
* Created by catcher92 on 2017/6/7. 
*/ 
@RunWith(SpringJUnit4ClassRunner.class) 
@ContextConfiguration(classes = {SpringConfig.class}) 
public class SpringDataSolrTest { 

    @Autowired 
    private SolrTemplate solrTemplate; 


    @Test 
    public void testAdd() { 
     Command command = new Command(); 
     command.setId("110"); 
     command.setCommand("template测试精彩"); 
     command.setDescription("spring data solr template测试精彩描述"); 
     command.setContents(Arrays.asList("测试精彩1", "2精彩测试")); 
     solrTemplate.saveBean(command); 
     solrTemplate.commit(); 
    } 

    @Test 
    public void testDel() { 
     solrTemplate.deleteById("110"); 
     solrTemplate.commit(); 
    } 
} 

Lorsque je teste la méthode testAdd() le message d'erreur comme ceci:

java.lang.NoSuchMethodError: org.apache.solr.common.SolrInputDocument: method <init>()V not found

Answer 1

Je fait face à la même question . C'est parce que dans Sorj 6.x le constructeur par défaut sans paramètres de SolrInputDocument() a été supprimé. Dans mon cas, j'ai utilisé une solution de contournement: la conversion de mon entité à SolrInputDocument, puis l'appel de la méthode saveBean().
