Solr7.x学习：使用spring-data-solr

King

1、maven配置

<dependency>
    <groupId>org.springframework.data</groupId>
    <artifactId>spring-data-solr</artifactId>
    <version>4.0.10.RELEASE</version>
</dependency>
<dependency>
    <groupId>org.apache.solr</groupId>
    <artifactId>solr-solrj</artifactId>
    <version>7.7.2</version>
</dependency>

2、application-solr.xml配置

<?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:solr="http://www.springframework.org/schema/data/solr"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
                https://www.springframework.org/schema/beans/spring-beans.xsd
                http://www.springframework.org/schema/data/solr
                https://www.springframework.org/schema/data/solr/spring-solr.xsd">

    <solr:solr-client id="solrClient" url="${solr.url}" />
    <solr:repositories base-package="com.zhi.demo.**.repository" />

    <bean name="solrTemplate" class="org.springframework.data.solr.core.SolrTemplate">
        <constructor-arg name="solrClient" ref="solrClient" />
        <!-- 根据Indexed注解创建不存在的字段 -->
        <property name="schemaCreationFeatures">
            <list>
                <value>CREATE_MISSING_FIELDS</value>
            </list>
        </property>
    </bean>
</beans>

注意schemaCreationFeatures选择，如果有CREATE_MISSING_FIELDS选择，Spring会在启动时根据Indexed注解在solr中创建没定义的field。关键代码：

3、创建Bean

Dept.java

package com.zhi.demo.dept.model;

import java.util.Date;

import org.springframework.data.annotation.Id;
import org.springframework.data.solr.core.mapping.Indexed;
import org.springframework.data.solr.core.mapping.SolrDocument;

/**
 * 部门信息，collection为对应的core名称，Indexed注解会自动在solr添加对应的field
 * 
 * @author zhi
 * @time 2016年12月22日09:55:08
 *
 */
@SolrDocument(collection = "dept")
public class Dept {
    /**
     * 部门ID
     */
    @Id
    @Indexed
    private String id;
    /**
     * 部门名称
     */
    @Indexed(type = "text_ik")
    private String name;
    /**
     * 创建时间
     */
    @Indexed(name = "createTime", type = "pdate")
    private Date createTime;
    /**
     * 备注
     */
    @Indexed(type = "text_ik")
    private String remark;

    public Dept() {
        super();
    }

    public Dept(String id, String name, Date createTime, String remark) {
        super();
        this.id = id;
        this.name = name;
        this.createTime = createTime;
        this.remark = remark;
    }

    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 Date getCreateTime() {
        return createTime;
    }

    public void setCreateTime(Date createTime) {
        this.createTime = createTime;
    }

    public String getRemark() {
        return remark;
    }

    public void setRemark(String remark) {
        this.remark = remark;
    }

}

Person.java

package com.zhi.demo.person.model;

import java.io.Serializable;
import java.util.Date;

import org.springframework.data.annotation.Id;
import org.springframework.data.solr.core.mapping.Indexed;

/**
 * 人员信息
 * 
 * @author 张远志
 * @time 2016年12月22日09:55:42
 *
 */
@SuppressWarnings("serial")
public class Person implements Serializable {
    /**
     * 主键
     */
    @Id
    @Indexed
    private String id;
    /**
     * 人员名称
     */
    @Indexed
    private String name;
    /**
     * 地址
     */
    @Indexed
    private String addr;
    /**
     * 年龄
     */
    private Integer age;
    /**
     * 部门ID
     */
    private String deptId;
    /**
     * 是否可用
     */
    private boolean usable;
    /**
     * 创建时间
     */
    private Date createTime;
    /**
     * 备注
     */
    private String remark;

    public Person() {
        super();
    }

    public Person(String id, String name, String addr, Integer age, String deptId, boolean usable, Date createTime,
            String remark) {
        super();
        this.id = id;
        this.name = name;
        this.addr = addr;
        this.age = age;
        this.deptId = deptId;
        this.usable = usable;
        this.createTime = createTime;
        this.remark = remark;
    }

    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 String getAddr() {
        return addr;
    }

    public void setAddr(String addr) {
        this.addr = addr;
    }

    public Integer getAge() {
        return age;
    }

    public void setAge(Integer age) {
        this.age = age;
    }

    public String getDeptId() {
        return deptId;
    }

    public void setDeptId(String deptId) {
        this.deptId = deptId;
    }

    public boolean isUsable() {
        return usable;
    }

    public void setUsable(boolean usable) {
        this.usable = usable;
    }

    public Date getCreateTime() {
        return createTime;
    }

    public void setCreateTime(Date createTime) {
        this.createTime = createTime;

    public String getRemark() {
        return remark;
    }

    public void setRemark(String remark) {
        this.remark = remark;
    }

4、使用Repository方式进行CRUD操作

创建DeptRepository.java

package com.zhi.demo.dept.repository;

import java.util.List;

import org.springframework.data.solr.repository.Query;
import org.springframework.data.solr.repository.SolrCrudRepository;

import com.zhi.demo.dept.model.Dept;

/**
 * 部门增删改查操作
 * 
 * @author zhi
 * @since 2019年9月27日14:05:15
 *
 */
public interface DeptRepository extends SolrCrudRepository<Dept, String> {

    @Query("name:?0 OR remark:?0")
    List<Dept> findList(String text);
}

知识兔View Code

定义Dept操作接口和实现

package com.zhi.demo.dept.service;

import java.util.List;

import com.zhi.demo.dept.model.Dept;

/**
 * 部门操作接口
 * 
 * @author zhi
 * @since 2019年9月27日13:12:26
 *
 */
public interface IDeptService {
    /**
     * 保存
     * 
     * @param model
     * @return
     */
    Dept save(Dept model);

    /**
     * 批量保存
     * 
     * @param models
     * @return
     */
    List<Dept> saveBatch(List<Dept> models);

    Dept findById(String id);

    List<Dept> list(String text);
}

import org.springframework.stereotype.Service;

import com.zhi.demo.dept.model.Dept;
import com.zhi.demo.dept.repository.DeptRepository;

/**
 * 部门操作接口实现
 *

 * @since 2019年9月27日13:12:26
 *
 */
@Service
public class DeptServiceImpl implements IDeptService {
    @Autowired
    private DeptRepository deptRepository;

    @Override
    public Dept save(Dept model) {
        deptRepository.save(model);
        return model;
    }

    @Override
    public List<Dept> saveBatch(List<Dept> models) {
        deptRepository.saveAll(models);
        return models;
    }

    @Override
    public Dept findById(String id) {
        Optional<Dept> optional = deptRepository.findById(id);
        if (optional.isPresent()) {
            return optional.get();
        }
        return null;
    }

    @Override
    public List<Dept> list(String text) {
        if (StringUtils.isEmpty(text)) {
            return IteratorUtils.toList(deptRepository.findAll().iterator());
        } else {
            return deptRepository.findList(text);
        }
    }
}

@ContextConfiguration(locations = { "classpath:application.xml", "classpath*:application-*.xml" })
public class DeptTest {
    private Logger logger = LogManager.getLogger(this.getClass());
    @Autowired
    private IDeptService deptService;

    @Test
    public void saveBatch() {
        try {

import java.util.List;

import com.zhi.demo.person.model.Person;

/**

 * 
 * @author zhi

public interface IPersonService {
    /**
     * 保存人员，
     * 
     * @param model
     * @return
     */
    Person save(Person model);

    /**
     * 批量保存人员
     * 
     * @param models
     * @return
     */
    List<Person> saveBatch(List<Person> models);

    /**
     * 根据ID查询人员信息
     * 
     * @param id
     * @return
     */
    Person findById(String id);

    /**
     * 根据关键字查询人员列表
     * 
     * @param text 与name和addr字段匹配
     * @return 列表长度由solr默认分页长度决定
     */
    List<Person> list(String text);

    /**
     * 根据可用状态查找人员列表
     * 
     * @param usable 与usable字段匹配
     * @return 列表长度由solr默认分页长度决定
