springboot构建solr查询实例

通过spring boot构建solr查询实例

spring boot

曾经使用spring我们需要各种各样的配置web.xml,配置springapplication.xml。真的很繁琐，要建一个项目框架出来，确实不太容易。而现在spring社区推出spring boot。完全不需要去管那些xml的配置了，springboot采用约定优于配置的思想，通过你项目所需的dependencies来自动配置框架。
springboot的特性：
1.自动配置文件
2.直接内置tomcat或jetty web服务器不需要打war包直接通过mvn spring-boot：run就可以运行。
3.只需要提供几个简单依赖就可以提供像springmvc，mybatis，jpa等框架支持。

springboot实例

该实例使用maven构建项目，以下是maven依赖。

<parent>    <groupId>org.springframework.boot</groupId>    <artifactId>spring-boot-starter-parent</artifactId>    <version>1.2.5.RELEASE</version>    <relativePath/> <!-- lookup parent from repository --></parent><properties>    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>    <java.version>1.8</java.version>    <guava.version>18.0</guava.version>    <commons.lang3.version>3.3.2</commons.lang3.version></properties><dependencies>    <dependency>        <groupId>org.springframework.boot</groupId>        <artifactId>spring-boot-starter-web</artifactId>    </dependency>    <dependency>        <groupId>org.springframework.boot</groupId>        <artifactId>spring-boot-starter-test</artifactId>        <scope>test</scope>    </dependency>    <dependency>        <groupId>com.github.pagehelper</groupId>        <artifactId>pagehelper</artifactId>        <version>4.0.0</version>    </dependency>    <dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId><version>5.1.17</version>

application.properties

spring.solr.host=http://192.168.219.134:8080/solrspring.solr.zkHost=192.168.219.134:2181,192.168.219.140:2181spring.solr.defaultCollection=demo

通过一个bean接收zk服务器相关属性

import org.springframework.boot.context.properties.ConfigurationProperties;@ConfigurationProperties(prefix="spring.solr")public class SolrConfig {private String host;private String zkHost;private String defaultCollection;public String getDefaultCollection() {    return defaultCollection;}public void setDefaultCollection(String defaultCollection) {    this.defaultCollection = defaultCollection;}public String getHost() {    return host;}public void setHost(String host) {    this.host = host;}public String getZkHost() {    return zkHost;}public void setZkHost(String zkHost) {    this.zkHost = zkHost;}

}

配置solrserver

@Configuration@EnableConfigurationProperties(SolrConfig.class)public class solrClientConfig {@Autowiredprivate SolrConfig solrConfig;private CloudSolrServer solrServer;@PreDestroypublic void close() {    if (this.solrServer != null) {        try {            this.solrServer.close();        } catch (IOException e) {            e.printStackTrace();        }    }}@Bean public CloudSolrServer SolrServer(){    if (StringUtils.hasText(this.solrConfig.getZkHost())) {        //solrClient = new CloudSolrClient(this.solrConfig.getZkHost());        solrServer = new CloudSolrServer(this.solrConfig.getZkHost());        solrServer.setDefaultCollection(this.solrConfig.getDefaultCollection());    }    return this.solrServer;}

}

接下来测试solr查询

@RestControllerpublic class HelloController {@Autowiredprivate CloudSolrServer solrserver;public String hello(){    return"say hello";}@RequestMapping("/test")public void test(){    ModifiableSolrParams params =new ModifiableSolrParams();    params.add("q","demo:父亲");    params.add("ws","json");    params.add("start","0");    params.add("rows","10");    QueryResponse response=null;        try{        response=solrserver.query(params);        SolrDocumentList results = response.getResults();        for (SolrDocument document:results) {        System.out.println( document.getFieldValue("demo"));        System.out.println(document.getFieldValue("id"));        }    }catch(Exception e){        e.getStackTrace();    }    System.out.println(response.toString());}

}
