Question

我在此之后配置了一个嵌入式solr服务器：https://stackoverflow.com/a/21848776/284236

它与pom文件中的以下内容完美配合：

<dependency>
    <groupId>org.springframework.data</groupId>
    <artifactId>spring-data-solr</artifactId>
    <version>1.0.0.RC1</version>
</dependency>
<dependency>
    <groupId>org.apache.solr</groupId>
    <artifactId>solr-core</artifactId>
    <version>4.1.0</version>
    <exclusions>
        <exclusion>
            <artifactId>slf4j-jdk14</artifactId>
            <groupId>org.slf4j</groupId>
        </exclusion>
    </exclusions>
</dependency>

我把它改为：

<dependency>
    <groupId>org.springframework.data</groupId>
    <artifactId>spring-data-solr</artifactId>
    <version>1.3.1.RELEASE</version>
</dependency>
<dependency>
    <groupId>org.apache.solr</groupId>
    <artifactId>solr-core</artifactId>
    <version>4.10.3</version>
    <exclusions>
        <exclusion>
            <artifactId>slf4j-jdk14</artifactId>
            <groupId>org.slf4j</groupId>
        </exclusion>
    </exclusions>
</dependency>

当我启动我的tomcat服务器时，我得到：

堆栈跟踪中没有任何内容可供我理解为什么会失败。

Answer 1

这是不同SOLR版本之间的冲突。

org.springframework.data有solr-core作为依赖关系。请参阅此maven-repository。

org.springframework.data 1.0.0.RC1恰好使用了您在旧示例中引用的SOLR 4.1.0。

Spring 1.3.1引用Solr 4.7.2。在这里查看maven-repository。

所以你可以从pom中删除solr依赖关系或切换到solr版本4.7.2。

在将spring-data-solr升级到1.3.1版时无法启动嵌入式solr服务器
