1.在工程中引入solr-solrj-4.10.3.jar

<dependency>
    <groupId>org.apache.solr</groupId>
    <artifactId>solr-solrj</artifactId>
    <version>4.10.3</version>
</dependency>

2.Solr的增刪改查

(1) schema.xml配置修改

<field name="stu_name"
 
 type="text_ik" indexed="true" stored="true" multiValued="false" /> 

<field name="stu_sex" type="int" indexed="true" stored="true" multiValued="false" /> 

<field name="stu_address" type="text_ik" indexed="true" stored="true" multiValued="false" />

(2)Student.java

package cn.ljh.ssm.test;

 
import org.apache.solr.client.solrj.beans.Field;

public class Student{
    @Field("id")
    private String id;
    @Field("stu_name")
    private String name;
    @Field("stu_sex")
    private int sex;
    @Field("stu_address")
    private String address;
    
    public String getId() {
        return
 
 id;
    }
    public void setId(String id) {
        this.id = id;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public int getSex() {
        return sex;
    }
    public void setSex(int sex) {
        this.sex = sex;
    }
    public String getAddress() {
        return address;
    }
    public void setAddress(String address) {
        this.address = address;
    }
    @Override
    public String toString() {
        return "Student [id=" + id + ", name=" + name + ", sex=" + sex
                + ", address=" + address + "]";
    }
}

(3) HttpSolrServerSingleton.java

package cn.ljh.ssm.test;

import org.apache.solr.client.solrj.impl.HttpSolrServer;

public class HttpSolrServerSingleton {
     //solr server URL指的時solr發布到web工程後的訪問路徑
     private final static String SolrURL = "http://192.168.137.168:8080/solr";
     //使用懶漢式單例中的靜態內部類方式
     private static class HttpSolrServerSingletonContainer{
         private static HttpSolrServer instance = new HttpSolrServer(
                 HttpSolrServerSingleton.SolrURL);
     }
     //solrServer是線程安全的，所以在使用時需要使用單例的模式，減少資源的消耗
     public static HttpSolrServer getInstance(){
            return HttpSolrServerSingletonContainer.instance;
     }

}
