如何为请求参数自定义拆分模式 [英] How to customize split-pattern for request parameter

问题描述

我的问题是我有以下网址:

My problem is that I have the following URL:

http://localhost:8080/shiSolrClient/app/shi/search?q=xyz&fq=author:"Max, Muster"

我有一个映射这些requestParameters的bean:

I have a bean that maps these requestParameters:

public class SearchParams {

    private String q = "";
    private String[] fq;

    // getters goes here...
}

我的问题是Spring会自动在逗号上分割fq参数.因此，在我的bean中，fq中有两个String:

My Problem is that Spring automatically split the fq-parameter on the comma. So in my bean there are two Strings in fq:

String[0]: author:"Max
String[1]: Muster"

我不要这种行为.我想要的是告诉Spring将'&'-令牌拆分为'，'-令牌.例如.

I don't want this behaviour. What I want is to tell Spring to split on '&'-tokens not on ','-tokens. E.g.

http://localhost:8080/shiSolrClient/app/shi/search?q=xyz&fq=author:"Max, Muster"&content:"someContent"

---

fq=     
String[0]: author:"Max, Muster"

String[1]: content:"someContent"

谁能告诉我如何在Spring MVC 3中将其归档

Can anyone tell me how to archive this in Spring MVC 3

我的控制器如下:

@RequestMapping(value = "search", method = RequestMethod.GET)
public String search(SearchParams searchParams, BindingResult bindResult, Model  
   model)  {

    SolrQuery solrQ = getBasicQuery(searchParams).setQuery(searchParams.getQ());
    for(String fq : searchParams.getFq()) {
        solrQ.setParam("fq", fq);
    }
    try {
        QueryResponse rsp = getSolrServer().query(solrQ);
        model.addAttribute("solrResults", transformResults(rsp.getResults(),
           rsp.getHighlighting(), searchParams, rsp));
        model.addAttribute("facetFields", transformFacets(rsp.getFacetFields(),
           rsp.getFacetDates(), searchParams));
        model.addAttribute("pagination", calcPagination(searchParams, 
           rsp.getResults()));
   ...
}

我的Spring-Config看起来像这样:

And my Spring-Config looks like this:

<!-- Enables the Spring MVC @Controller programming model -->
<annotation-driven />

<!-- Handles HTTP GET requests for /resources/** -->
<resources mapping="/resources/**" location="/resources/" />

<!-- Configure Apache Tiles for the view -->
<beans:bean id="tilesConfigurer" 
        class="org.springframework.web.servlet.view.tiles2.TilesConfigurer">
   <beans:property name="definitions">
          <beans:list>
      <beans:value>/WEB-INF/views/layout/layouts.xml</beans:value>
      <beans:value>/WEB-INF/views/hitlist/views.xml</beans:value>
      </beans:list>
   </beans:property>
</beans:bean>

<beans:bean id="viewResolver"
          class="org.springframework.web.servlet.view.UrlBasedViewResolver">
   <beans:property name="requestContextAttribute" value="requestContext"/>
   <beans:property name="viewClass" 
           value="org.springframework.web.servlet.view.tiles2.TilesView"/>
</beans:bean>

<beans:bean id="messageSource"
      class="org.springframework.context.support.ResourceBundleMessageSource">
   <beans:property name="basenames">
      <beans:list>
      <beans:value>global</beans:value>
      <beans:value>hitlist</beans:value>
      <beans:value>local/messages</beans:value>
      </beans:list>
   </beans:property>
</beans:bean>

    <!-- Scans within the base package of the application for @Components to configure 
          as beans -->
<context:component-scan base-package="com.shi.solrclient.web" />

推荐答案

我在尝试将@RequestParameter与List一起使用时遇到了类似的问题(它总是被逗号分隔.

I ran into a similar problem trying to use a @RequestParameter with List (it kept getting chopped up at commas.

我想出的解决方案是在控制器方法中使用WebRequest参数，这使我可以使用request.getParameterValues("blar")

The solution I came up with was to use a WebRequest parameter in my controller method, which allows me to use request.getParameterValues("blar")

@RequestMapping(value = "search", method = RequestMethod.GET)
public String search(WebRequest req, BindingResult bindResult, Model  model)  {
    String[] searchParams = req.getParameterValues("fq")
