品优购_关键字solr搜索

第一步:准备工作

因为service层需要将数据发布到dubbo上,所以在tomcat启动后会直接寻找web.xml, 根据web.xml加载spring/applicationContext_service.xml 和solr.xml (因此此处要从solr中获取数据)

web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xmlns="http://java.sun.com/xml/ns/javaee"
         xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
         version="2.5">

<servlet>
      <servlet-name>springmvc</servlet-name>
      <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
      <init-param>
           <param-name>contextConfigLocation</param-name>
           <param-value>classpath*:spring/applicationContext*.xml</param-value>
      </init-param>
      <load-on-startup>2</load-on-startup>
</servlet>
<servlet-mapping>
      <servlet-name>springmvc</servlet-name>
      <url-pattern>*.do</url-pattern>
</servlet-mapping>
</web-app>

找到spring/applicationContext_service.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:dubbo="http://code.alibabatech.com/schema/dubbo"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://code.alibabatech.com/schema/dubbo http://code.alibabatech.com/schema/dubbo/dubbo.xsd">
         <!--注入dubbo-->
         <dubbo:protocol name="dubbo" port="20884"></dubbo:protocol>
         <dubbo:application name="pyg_search_service"></dubbo:application>
         <dubbo:registry address="zookeeper://192.168.35.200:2181"></dubbo:registry>
         <dubbo:annotation package="com.pyg.search.Impl"></dubbo:annotation>
</beans>

applicationContext_solr.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:solr="http://www.springframework.org/schema/data/solr"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/data/solr http://www.springframework.org/schema/data/solr/spring-solr.xsd">

        <!--solr服务器地址-->
        <solr:solr-server id="solr" url="http://127.0.0.1:8080/solr"></solr:solr-server>
        <!--solr模板获取-->
        <bean id="solrTemplate" class="org.springframework.data.solr.core.SolrTemplate">
            <constructor-arg ref="solr"></constructor-arg>
        </bean>
</beans>

 

总结: 其实applicationContext_solr.xml 和applicationContext_service.xml的意思是 

applicationContext_solr.xml:  获取了solr地址,然后将地址信息作为构造进入solrTemplate的bean获取到了实例化对象,这样在本项目中就可以通过@Autoware进行注入这个bean使用了

applicationContext_service.xml:  将本项目的某些包交给dubbo进行管理, 所以里面注册了dubbo的地址,命名和端口号,这样只需要在包里面相应的类上加上@Service (阿里的) 标签就可以将其服务注册到dubbo远程服务器中,方便其他web层的调用

 

之后的步骤就如上图所示:基本代码编写了,由于此处难度较小,可以参考笔记day09进行书写.
