List<实体>与List<String>数据互转

1、List<实体>数据：

public List<Device> queryOSDevice(String cpu,String ip,String name){

    String sql = null;

    if(cpu.equals("os_xp")){

        sql = "from "+this.clazz.getName()+" this WHERE this.os.id = (select id from Os o where o.name = 'com.vrv.common.system.os.WindowsXP') ";

    }else if(cpu.equals("os_7")){

    }else if(cpu.equals("os_95")){

        sql = "from "+this.clazz.getName()+" this WHERE this.os.id = (select id from Os o where o.name = 'com.vrv.common.system.os.Windows95') ";

    }else if(cpu.equals("os_me")){

        sql = "from "+this.clazz.getName()+" this WHERE this.os.id = (select id from Os o where o.name = 'com.vrv.common.system.os.WindowsMe') ";

        return getSession().createQuery(sql)

                .setParameter("ip", ip)

    }

    return getSession().createQuery(sql).list();

}

2、List<String>数据：

public List<String> queryOSDevice(String cpu,String ip,String name){

    String sql = null;

    List<String> osDevice = new ArrayList<String>();

    if(cpu.equals("os_xp")){

        sql += "and this.name = '" + name + "'";

    }

    osDevice = getSession().createQuery(sql).list();

    return osDevice;

}

　　注意：List<String>里面标红处需要注意的项，看下面这篇博客：常见Hibernate报错处理：出现“org.hibernate.QueryException: could not resolve property”和 is not mapped和could not locate named parameter错误的解决

List<Object>：

public List<Object> queryCountByOsAndOrgname(String cpu,String orgName) {

    List<Object> list = new ArrayList<Object>();

    String sql = null;

    if(cpu.equals("os_xp")){

        sql = "select count(*) from " + this.clazz.getName() + " this where this.os.id = (select id from Os o where o.name = 'com.vrv.common.system.os.WindowsXP') ";

    }else if(cpu.equals("os_7")){

        sql = "select count(*) from " + this.clazz.getName() + " this where this.os.id = (select id from Os o where o.name = 'com.vrv.common.system.os.Windows7') ";

    }else if(cpu.equals("os_win8")){

        sql = "select count(*) from " + this.clazz.getName() + " this where this.os.id = (select id from Os o where o.name = 'com.vrv.common.system.os.Windows81') ";

    }else if(cpu.equals("os_win10")){

        sql = "select count(*) from " + this.clazz.getName() + " this where this.os.id = (select id from Os o where o.name = 'com.vrv.common.system.os.Windows10InsiderPreview') ";

    }else if(cpu.equals("os_vista")){

        sql = "select count(*) from " + this.clazz.getName() + " this where this.os.id = (select id from Os o where o.name = 'com.vrv.common.system.os.WindowsVista') ";

    }else if(cpu.equals("os_2003")){

        sql = "select count(*) from " + this.clazz.getName() + " this where this.os.id = (select id from Os o where o.name = 'com.vrv.common.system.os.WindowsServer2003') ";

    }else if(cpu.equals("os_98")){

        sql = "select count(*) from " + this.clazz.getName() + " this where this.os.id = (select id from Os o where o.name = 'com.vrv.common.system.os.Windows98') ";

    }else if(cpu.equals("os_95")){

        sql = "select count(*) from " + this.clazz.getName() + " this where this.os.id = (select id from Os o where o.name = 'com.vrv.common.system.os.Windows95') ";

    }else if(cpu.equals("os_me")){

        sql = "select count(*) from " + this.clazz.getName() + " this where this.os.id = (select id from Os o where o.name = 'com.vrv.common.system.os.WindowsMe') ";

    }else if(cpu.equals("os_nt")){

        sql = "select count(*) from " + this.clazz.getName() + " this where this.os.id = (select id from Os o where o.name = 'com.vrv.common.system.os.WindowsNt') ";

    }else if(cpu.equals("os_2000")){

        sql = "select count(*) from " + this.clazz.getName() + " this where this.os.id = (select id from Os o where o.name = 'com.vrv.common.system.os.Windows2000') ";

    }

    if(!"".equals(orgName)){

        sql += "and this.organization.name = '" + orgName + "'";

    }

    Number number = (Number)getSession().createQuery(sql).uniqueResult();

    if(number==null){

        number = ;

    }

    JSONObject jsonObject = new JSONObject();

    jsonObject.put(orgName, number);

    list.add(jsonObject);

    return list;

}

List<Object>数据需要改一下：就是根据os查出来所有的数据，然后再根据orgName去分组，需要各orgName分组的数目；需要传递过去的接口数据类型如下：
[{"classid":"姚佳豪","value":1}, {"classid":"测试一部","value":1}, {"classid":"王明明","value":3}, {"classid":"陈锋","value":2}, {"classid":"黄睿","value":1}]

根据数据库查出来的数据如下：

@SuppressWarnings("unchecked")

public List<Object> queryCountByOsAndOrgname(String cpu,Integer orgName) {

    List<Object> list = new ArrayList<Object>();

    String sql = null;

    if(cpu.equals("os_xp")){

        sql = "select count(*),c.name from cems_device d,cems_organization c "

                + "where this.os.id = (select id from Os o where o.name = 'com.vrv.common.system.os.WindowsXP') ";

    }else if(cpu.equals("os_7")){

        sql = "select count(*),c.name from cems_device d,cems_organization c "

                + "where d.osId = (select id from cems_dict_os o where o.name = 'com.vrv.common.system.os.Windows7') ";

    }else if(cpu.equals("os_win8")){

        sql = "select count(*),c.name from cems_device d,cems_organization c "

                + "where this.os.id = (select id from Os o where o.name = 'com.vrv.common.system.os.Windows81') ";

    }else if(cpu.equals("os_win10")){

        sql = "select count(*),c.name from cems_device d,cems_organization c "

                + "where this.os.id = (select id from Os o where o.name = 'com.vrv.common.system.os.Windows10InsiderPreview') ";

    }else if(cpu.equals("os_vista")){

        sql = "select count(*),c.name from cems_device d,cems_organization c "

                + "where this.os.id = (select id from Os o where o.name = 'com.vrv.common.system.os.WindowsVista') ";

    }else if(cpu.equals("os_2003")){

        sql = "select count(*),c.name from cems_device d,cems_organization c "

                + "where this.os.id = (select id from Os o where o.name = 'com.vrv.common.system.os.WindowsServer2003') ";

    }else if(cpu.equals("os_98")){

        sql = "select count(*),c.name from cems_device d,cems_organization c "

                + "where this.os.id = (select id from Os o where o.name = 'com.vrv.common.system.os.Windows98') ";

    }else if(cpu.equals("os_95")){

        sql = "select count(*),c.name from cems_device d,cems_organization c "

                + "where this.os.id = (select id from Os o where o.name = 'com.vrv.common.system.os.Windows95') ";

    }else if(cpu.equals("os_me")){

        sql = "select count(*),c.name from cems_device d,cems_organization c "

                + "where this.os.id = (select id from Os o where o.name = 'com.vrv.common.system.os.WindowsMe') ";

    }else if(cpu.equals("os_nt")){

        sql = "select count(*),c.name from cems_device d,cems_organization c "

    }

    if(- == orgName){

        sql += "and d.organizationId = c.id group by d.organizationId ";

    }

    List<Object[]> listobj = getSession().createSQLQuery(sql).list();

    //注意List里面是Object[]对象数组的类型,这样下面listobj.get(i)[1]，才可以获取到

    for(int i = ; i < listobj.size(); i++){

        JSONObject jsonObject = new JSONObject();

        jsonObject.put("classid", listobj.get(i)[]);

        jsonObject.put("value", listobj.get(i)[]);

        list.add(jsonObject);

    }

    return list;

}

3、List<Device>实体数据：

public List<Device> queryOSDevice(String cpu,String ip,String name,String orgname){

    String sql = null;

    List<Device> osDevice = new ArrayList<Device>();

    if(cpu.equals("os_xp")){

        sql = "from "+this.clazz.getName()+" this WHERE this.os.id = (select id from Os o where o.name = 'com.vrv.common.system.os.WindowsXP') ";

    }else if(cpu.equals("os_7")){

        sql = " from "+this.clazz.getName()+" this WHERE this.os.id = (select id from Os o where o.name = 'com.vrv.common.system.os.Windows7') ";

    }else if(cpu.equals("Os_Win8")){

        sql = " from "+this.clazz.getName()+" this WHERE this.os.id = (select id from Os o where o.name = 'com.vrv.common.system.os.Windows81') ";

    }else if(cpu.equals("Os_Win10")){

        sql = " from "+this.clazz.getName()+" this WHERE this.os.id = (select id from Os o where o.name = 'com.vrv.common.system.os.Windows10InsiderPreview') ";

    }else if(cpu.equals("os_vista")){

        sql = " from "+this.clazz.getName()+" this WHERE this.os.id = (select id from Os o where o.name = 'com.vrv.common.system.os.WindowsVista') ";

    }else if(cpu.equals("os_2003")){

        sql = " from "+this.clazz.getName()+" this WHERE this.os.id = (select id from Os o where o.name = 'com.vrv.common.system.os.WindowsServer2003') ";

    }else if(cpu.equals("os_98")){

        sql = " from "+this.clazz.getName()+" this WHERE this.os.id = (select id from Os o where o.name = 'com.vrv.common.system.os.Windows98') ";

    }else if(cpu.equals("os_95")){

        sql = " from "+this.clazz.getName()+" this WHERE this.os.id = (select id from Os o where o.name = 'com.vrv.common.system.os.Windows95') ";

    }else if(cpu.equals("os_me")){

        sql = " from "+this.clazz.getName()+" this WHERE this.os.id = (select id from Os o where o.name = 'com.vrv.common.system.os.WindowsMe') ";

    }else if(cpu.equals("os_nt")){

        sql = " from "+this.clazz.getName()+" this WHERE this.os.id = (select id from Os o where o.name = 'com.vrv.common.system.os.WindowsNt') ";

    }else if(cpu.equals("os_2000")){

        sql = " from "+this.clazz.getName()+" this WHERE this.os.id = (select id from Os o where o.name = 'com.vrv.common.system.os.Windows2000') ";

    }

    if(!"".equals(ip)){

        sql += "and this.ip = '" + ip +"'";

    }

    if(!"".equals(name)){

        sql += "and this.name = '" + name + "'";

    }

    if(!"".equals(orgname)){

        sql += "and this.organization.name = '" + orgname + "'";

    }

    osDevice = getSession().createQuery(sql).list();

    return osDevice;

}

　　表里关联的是：

　　映射XML文件：

<!-- 所属组织机构 -->

<many-to-one name="organization" class="com.vrv.cems.mgr.domain.Organization" not-null="true" column="organizationId" not-found="ignore"/>

　　这种写法：this.organization.name，能取到organization表里的name。
