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
[html] view plain copy
xsi:schemaLocation=" http://maven.apache.org/POM/4.0.0
http://maven.apache.org/xsd/maven-4.0.0.xsd">
;
4.0.0
com.millery.spring_solr
spring-solr
0.0.1-SNAPSHOT
war
org.springframework
spring-context
4.1.3.RELEASE
org.springframework
spring-beans
4.1.3.RELEASE
org.springframework
spring-jdbc
4.1.3.RELEASE
org.springframework
spring-aspects
4.1.3.RELEASE
org.apache.solr
solr-solrj
4.10.1
junit
junit
4.10
test
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:
[html] view plain copy
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">
;
solr.properties配置文件的内容:
[html] view plain copy
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
[html] view plain copy
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">
;
class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
classpath:solr.properties
[html] view plain copy
第四步:写测试代码
User实体类:
[html] view plain copy
br/>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:
[html] view plain copy
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:
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);
}
}
来自CODE的代码片
SpringSolrTest.java
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。
