我认为此错误与solrj与spring的库冲突有关，但我无法解决此问题，我也删除了maven的缓存(.m2文件夹)并再次重新导入依赖项，但无法正常工作，并且我的pom.xml文件如下所示:

I think that this error related to library conflict of solrj with spring but i cant solve this , also i delete cache of maven (.m2 folder) and reimport dependency again but not work and my pom.xml file like below :

这是我对solr的配置:

and this is my configuration for solr :

    @Bean
public SolrClient solrClient() {
    return new HttpSolrClient(environment.getRequiredProperty(PROPERTY_NAME_SOLR_SERVER_URL));
}

请帮助我解决此错误，谢谢...

please help me to solve this error , thanks...

我的项目结构中有5个Maven子项目.这些子项目中的两个有一个依赖关系，该依赖关系存在于两个名称不同但内容重叠的不同jar中.我反编译了所有依赖项，以识别出重复的部分，并删除了更苗条的jar依赖项.

I have 5 maven subprojects in my project structure. Two of these sub-projects had a dependency that was present in 2 different jars with different names but with overlapping contents. I decompiled all my dependencies to identify what the duplicated part was and removed the slimmer jar dependency.

我的建议:这很可能是类路径中的重复项.梳理您的依赖项并查找重复项.通过重复，我不仅指的是依赖项的jar名称，还包括这些jar中的内容和类文件.

My suggestion: This is most likely a duplicate in the classpath. Comb through your dependencies and look for duplicates. By duplicates, I don't mean just the jar names of the dependencies, but the contents and class files in those jars.
