solrj之solr基本应用!

需要打开经过和solr整合的tomcat服务器：

修改solr的conf文件夹下:schema.xml,自定义搜索字段！

<field name="msg_title" type="textComplex" stored="true" indexed="true"/>   <field name="msg_content" type="textComplex" stored="true" indexed="true" multiValued="true"/> <!--该字段用于数组list类型,也可以用于定义copyfile类型-->    <field name="msg_all" type="textComplex" stored="false" indexed="true" multiValued="true" />

copyfile类型，踊跃or类型的的搜索，如想搜索title和content类型中包含某字段,可以指定：msg_all:xxx

<copyField source="msg_title" dest="msg_all"/><copyField source="msg_content" dest="msg_all"/>

实体类：

public class Message {private String id;private String title;private String[] content;public Message() {super();// TODO Auto-generated constructor stub}public Message(String id, String title, String[] content) {super();this.id = id;this.title = title;this.content = content;}public String getId() {return id;}@Fieldpublic void setId(String id) {this.id = id;}public String getTitle() {return title;}@Field("msg_title")public void setTitle(String title) {this.title = title;}public String[] getContent() {return content;}//添加是个数组---<field name="msg_content" type="textComplex" stored="true" indexed="true" multiValued="true"/>@Field("msg_content")public void setContent(String[] content) {this.content = content;}}
