java.lang.IllegalArgumentException:环境不能为null [英] java.lang.IllegalArgumentException: Environment must not be null

问题描述

我尝试设置一个基本的SolrRepository应用，并在ApplicationContext加载期间出现此错误:

I try to setup a basic SolrRepository app and Have this error during ApplicationContext load :

Caused by: java.lang.IllegalArgumentException: Environment must not be null!

这是我的ConfigClass:

Here is my ConfigClass :

@Configuration
@PropertySource("classpath:sandbox.properties")
@ComponentScan("sandbox.solr")
@EnableSolrRepositories(basePackages = { "sandbox.solr.repository" }, multicoreSupport = true)
public class StreamingSolrConf {

    @Resource
    private Environment env;

    @Bean
    public SolrServer solrServer() {
        return new HttpSolrServer(env.getRequiredProperty("solr.server.url"));
    }

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

还有我的存储库界面:

package sandbox.solr.repository;

import org.springframework.data.solr.repository.SolrCrudRepository;

public interface SandboxRepository extends SolrCrudRepository<Document, String> {
}

无法弄清楚为什么没有在正确的时间在Spring上下文内注入环境. 我错过了什么 ? 问候.

Can't figure why the Environment is not injected at the right time inside the spring context. What did I miss ? Regards.

推荐答案

只需解决此问题(请参阅原始问题的注释):

Just to solve this Question (see comments on original question):

他在spring-3.2.8.RELEASE中同时使用了spring-data-solr-1.2.1.RELEASE. 降级到spring-data-solr-1.1.3-RELEASE并保留spring-3.2.8.RELEASE或升级到spring-3.2.9.RELEASE以保留spring-data-solr-1.2.1.RELEASE将解决此问题.

He was using the spring-data-solr-1.2.1.RELEASE with spring-3.2.8.RELEASE either. Downgrading to spring-data-solr-1.1.3-RELEASE and stay with spring-3.2.8.RELEASE or upgrade to spring-3.2.9.RELEASE to keep spring-data-solr-1.2.1.RELEASE will solve the issue.
