Java 在Spring Data Solr 1.5.4中创建自定义Solr查询时发生AbstractMethodError

我在我的项目中使用SpringBoot1.4、SpringDataJPA1.10.2、SpringDataSolr1.5.4和Solr4.10.4。到目前为止，我的程序和Solr之间的通信工作正常。我可以使用

SolrCrudRepository

提供的方法

save（）

和

findAll（）

当我尝试向存储库添加新查询时，就会出现问题。我尝试使用所有三种可用方法（命名为querys、query annotation和method name）执行此操作，但在启动webapp时都会导致相同的错误：

SolrContext

是这样创建的：

package com.my.project.mapping;

import org.apache.solr.client.solrj.beans.Field;
import org.springframework.data.annotation.Id;

import java.util.UUID;

public class SolrEntry {

    @Id
    @Field
    private String id;

    @Field
    private String message;

    @Field
    private String channel;

    @Field
    private String user;

    @Field
    private String timestamp;

    public SolrEntry(String channel, String user, String message, String timestamp) {
        this.id = UUID.randomUUID().toString();
        this.channel = channel;
        this.user = user;
        this.message = message;
        this.timestamp = timestamp;
    }
    //Getter and Setter omitted
}

package com.my.project.config;

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

import javax.annotation.Resource;

@Configuration
@EnableSolrRepositories(basePackages = "com.my.project.repository.solr", multicoreSupport = true)
public class SolrContext {

    static final String SOLR_HOST = "solr.host";

    @Resource
    private Environment environment;

    @Bean
    public SolrServer solrServer() {
        return new HttpSolrServer(environment.getRequiredProperty(SOLR_HOST));
    }

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

除了官方的配置之外，我还遵循了这一点，在谷歌搜索这个问题时没有找到解决方案。

提前感谢您的帮助。

经过反复尝试，我终于找到了答案。Spring Boot 1.4和Spring Data Solr 1.5.4似乎存在问题。我降级到Spring Boot 1.3.7，它立即起作用

package com.my.project.config;

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

import javax.annotation.Resource;

@Configuration
@EnableSolrRepositories(basePackages = "com.my.project.repository.solr", multicoreSupport = true)
public class SolrContext {

    static final String SOLR_HOST = "solr.host";

    @Resource
    private Environment environment;

    @Bean
    public SolrServer solrServer() {
        return new HttpSolrServer(environment.getRequiredProperty(SOLR_HOST));
    }

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