hibernate中数组如何对应到数据库中

publicclass POJOimplements java.io.Serializable {private String[] strs;public String[] getStrs() {return strs; }publicvoid setStrs(String[] strs) {this.strs= strs; }}

为什么不换种思维？

Java code

public class POJO implements java.io.Serializable {    private Integer id;    private String strs;        public Integer getId(){       return id;    }    public void setId(Integer id){       this.id = id;    }    public String getStrs() {        return strs;    }        public void setStrs(String strs) {        this.strs = strs;    }}//hbm.xml，假设POJO类路径为com.csdn.bean.POJO<?xml version="1.0" encoding="utf-8"?><!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN""http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"><!--     Mapping file autogenerated by MyEclipse Persistence Tools--><hibernate-mapping>    <class name="com.csdn.bean.POJO" table="pojo">        <id name="id" type="integer">            <column name="ID" />            <generator class="increment" />        </id>        <property name="strval" type="string">            <column name="field_strval" not-null="true"/>        </property>    </class></hibernate-mapping>

当要使用strs时：
String strs = pojo.getStrs();
String[] result = strs.split(",");
