Question

从solrResponse对象获取bean时发生问题。虽然结果从数据库返回并且也会响应。何时，我尝试运行resp.getBeans(UserObj.class); 它返回零结果当我从solr admin提示符运行查询时，它返回了适当的结果。因此，管理员方面已正确配置，因为我无法从结果中提取POJO对象。

请浏览UserObj.java和Controller代码。还粘贴了schema.xml和db-data-config.xml代码。

- schema.xml中

 <fields>
<field name="userId" type="sint" indexed="true" stored="true" required="true"       omitNorms="true" /> 
<field name="firstName" type="string" indexed="true" stored="true" required="true" omitNorms="true" />
<field name="lastName" type="string" indexed="true" stored="true" omitNorms="true" />
<field name="login" type="string" indexed="true" stored="true" omitNorms="true" />
<field name="email" type="string" indexed="true" stored="true" omitNorms="true" />
<field name="status" type="string" indexed="true" stored="true" omitNorms="true" />
<field name="sig_address" type="string" indexed="true" stored="true" omitNorms="true"     />
<!--<dynamicField name="roles_*" type="string" indexed="true" stored="true"  omitNorms="true" />-->
<field name="roles_ids" type="sint" indexed="true" stored="true" multiValued="true" omitNorms="true" />
</fields>
<uniqueKey>userId</uniqueKey>
<defaultSearchField>userId</defaultSearchField>

- DB-数据-config.xml中

<dataConfig>

<dataSource driver="com.mysql.jdbc.Driver" url="dburl" user="user" password="password" />
<document name="users">
    <entity name="user" pk ="userId"  query="select userId, firstName, lastName, login,email,status,sig_address from USER"
        deltaImportQuery="select userId, firstName, lastName, login, sig_address,email,status from USER where userId='${dataimporter.delta.userId}'" 
        deltaQuery="select userId from USER where timeStamp >= '${dataimporter.last_index_time}'" >
        <field column="userId," name="userId" />
        <field column="firstName" name="firstName" />
        <field column="lastName" name="lastName" />
        <field column="login" name="login" />
        <field column="email" name="email" />
        <field column="status" name="status" />
        <field column="sig_address" name="sig_address" />
        <!--
        <entity  name="user_roles" pk="refid" transformer="script:addRoles" query="select usd.refid, usd.refvalue , usr_bak.name from USER_SETDATAS usd, USER_ROLES_BAK usr_bak where usd.refvalue = usr_bak.id
             and usd.refid=${user.userId} and usd.fieldname='ROLES'"
            deltaQuery="select refid from USER_SETDATAS where last_modified >= '${dataimporter.last_index_time}'"
            deletedPkQuery="select refid from USER_SETDATS_BAK_LOG where timeStamp >= '${dataimporter.last_index_time}'"
            parentDeltaQuery="select userId from USER where userid=${user_roles.refid}" >
            <field column="refvalue" name="roles_ids" />
        </entity>
        -->
    </entity>
</document>

- 控制器代码

userSolrBean.setParser(new XMLResponseParser());
            SolrQuery query = new SolrQuery();
            String userQuery = "";
            if(email!=null)
                userQuery="email :*"+email+"*";
            if(login!=null)
                userQuery="login :*"+login+"*";
            if(email!=null && login!=null)
                userQuery="email :*"+email+"* OR login:*"+login+"*";
            log.info("solr query for user search is :"+userQuery);
            query.set("q",userQuery);
            query.setRows(0);
            query.setFacetLimit(-1);
            query.setFacetMinCount(1);
            QueryResponse resp= userSolrBean.query(query, METHOD.POST);
            filteredUsers=resp.getBeans(UserObj.class);

您必须使用适当的值来返回要返回的对象数。零将执行查询并计算符合给定条件的文档。

query.setRows(10);  //return 10 documents
query.setStart(0); //starting at the first

Solrj getBeans（）没有返回任何结果
