maven项目下solr和spring的整合配置 maven项目下solr和spring的整合配置详解
JavaIT程序员 人气:0前言:
solr和spring整合其实很简单,只要注意导入依赖的配置文件即可。废话不多说,上代码。
第一步:编写maven项目的pom文件,导入依赖
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">; <modelVersion>4.0.0</modelVersion> <groupId>com.millery.spring_solr</groupId> <artifactId>spring-solr</artifactId> <version>0.0.1-SNAPSHOT</version> <packaging>war</packaging> <!-- 添加依赖 --> <dependencies> <!-- Spring依赖 --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>4.1.3.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-beans</artifactId> <version>4.1.3.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>4.1.3.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aspects</artifactId> <version>4.1.3.RELEASE</version> </dependency> <!--solr客户端solrj的依赖 --> <dependency> <groupId>org.apache.solr</groupId> <artifactId>solr-solrj</artifactId> <version>4.10.1</version> </dependency> <!-- junit测试 --> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.10</version> <scope>test</scope> </dependency> </dependencies> </project>
第二步:编写applicationContext-solr.xml和solr.properties配置文件
applicationContext-solr.xml配置文件的内容:
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context" xmlns:mvc="http://www.springframework.org/schema/mvc" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">; <!--定义solr的server--> <bean id="httpSolrServer" class="org.apache.solr.client.solrj.impl.HttpSolrServer"> <constructor-arg index="0" value="${solr.Url}"/> <!-- 设置响应解析器 --> <property name="parser"> <bean class="org.apache.solr.client.solrj.impl.XMLResponseParser"/> </property> <!-- 设置重试次数--> <property name="maxRetries" value="${solr.maxRetries}"/> <!-- 建立连接的最长时间 --> <property name="connectionTimeout" value="${solr.connectionTimeout}"/> </bean> </beans>
solr.properties配置文件的内容:
solr.Url=http://127.0.0.1:8983/millery solr.maxRetries=1 solr.connectionTimeout=500
第三步:编写applicationContext.xml配置文件
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context" xmlns:mvc="http://www.springframework.org/schema/mvc" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">; <!--配置service的包扫描,自动注入Service --> <context:component-scan base-package="com.millery" /> <!-- 使用spring自带的占位符替换功能 --> <bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"> <!-- 允许JVM参数覆盖 --> <property name="systemPropertiesModeName" value="SYSTEM_PROPERTIES_MODE_OVERRIDE" /> <!-- 忽略没有找到的资源文件 --> <property name="ignoreResourceNotFound" value="true" /> <!-- 配置资源文件 --> <property name="locations"> <list> <value>classpath:solr.properties</value> </list> </property> <a target=_blank href="http://write.blog.csdn.net/User.java" rel="external nofollow" ><span style="color: rgb(0, 0, 255);"></span></a><pre name="code" class="html"> </bean> </beans>
第四步:写测试代码
User实体类:
package com.millery.spring_solr.pojo; /** * * @项目名称:spring-solr @类名称:User @类描述:用户实体类 br/> * @创建人:millery @创建时间:2015年11月5日 上午10:42:43 @version: br/> */ public class User { private Long id;// 用户编号 private String username;// 用户名 private String loginPwd;// 用户登录密码 private String email;// 用户邮箱 public Long getId() { return id; } public void setId(Long id) { this.id = id; } public String getUsername() { return username; } public void setUsername(String username) { this.username = username; } public String getLoginPwd() { return loginPwd; } public void setLoginPwd(String loginPwd) { this.loginPwd = loginPwd; } public String getEmail() { return email; } public void setEmail(String email) { this.email = email; } @Override public String toString() { return "User [id=" + id + ", username=" + username + ", loginPwd=" + loginPwd + ", email=" + email + "]"; } }
SpringSolr类:
import org.apache.solr.client.solrj.SolrQuery; import org.apache.solr.client.solrj.SolrServerException; import org.apache.solr.client.solrj.impl.HttpSolrServer; import org.apache.solr.client.solrj.response.QueryResponse; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Component; import com.millery.spring_solr.pojo.User; /** * * @项目名称:spring-solr br/> */ import org.apache.solr.client.solrj.SolrQuery; import org.apache.solr.client.solrj.SolrServerException; import org.apache.solr.client.solrj.impl.HttpSolrServer; import org.apache.solr.client.solrj.response.QueryResponse; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Component; import com.millery.spring_solr.pojo.User; /** * * @项目名称:spring-solr @类名称:SpringSolrTest @类描述:测试类 br/> * @创建人:millery @创建时间:2015年11月5日 上午10:48:57 @version: br/> */ @Component public class SpringSolr { br/> @Autowired private HttpSolrServer httpSolrServer; public User getUser(Long id) throws SolrServerException { //创建查询条件 SolrQuery query = new SolrQuery(); query.setQuery("id:" + id); //查询并返回结果 QueryResponse queryResponse = this.httpSolrServer.query(query); return (User) queryResponse.getBeans(User.class); } }
SpringSolrTest类:
SpringSolrTest.java
package com.millery.spring_solr.test; import org.apache.solr.client.solrj.SolrServerException; import org.junit.Before; import org.junit.Test; import org.springframework.context.ApplicationContext; import org.springframework.context.support.ClassPathXmlApplicationContext; import com.millery.spring_solr.pojo.User; public class SpringSolrTest { private SpringSolr springSolr;br/>@Before public void setUp() throws Exception { // 初始化Spring容器 ApplicationContext applicationContext = new ClassPathXmlApplicationContext( "applicationContext.xml", "applicationContext-solr.xml"); //获取对象 this.springSolr = applicationContext.getBean(SpringSolr.class);br/>} @Test public void test() throws SolrServerException { // 测试方法,输出结果 User user = springSolr.getUser((long) 1); System.out.println(user); } }
运行代码结果:
org.apache.solr.client.solrj.SolrServerException: IOException occured when talking to server at: http://127.0.0.1:8983/millery
这里抛异常时因为我本机上没有安装solr,无法连接solr,此时说明代码已经没有问题,可以执行查询操作了。
总结建工程时存在的小问题:
1、在建立工程时打包方式使用jar和war的选择可能存在纠结,只想说不用纠结,选哪个都是一样的。
2、在工程pom.xml配置文件配置完成后,可能会出现下图的报错问题,此时就需要简单的处理一下就可以了。
