使用solrj查询数据（java代码）

实体类Student,添加Field注解

package com.cs.solr.entity;

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

public class Student {
    @Field("id")
    private Integer id;
    @Field("name")
    private String name;
    @Field("gender")
    private String gender;
    @Field("major")
    private String major;
    @Field("grade")
    private String grade;
    

    public Student() {
        super();
    }

    public Integer getId() {
        return id;
    }

    public void setId(Integer id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getGender() {
        return gender;
    }

    public void setGender(String gender) {
        this.gender = gender;
    }

    public String getMajor() {
        return major;
    }

    public void setMajor(String major) {
        this.major = major;
    }

    public String getGrade() {
        return grade;
    }

    public void setGrade(String grade) {
        this.grade = grade;
    }
}
