Question

我正在尝试在我的项目中实现Datatables spring。

在RoleController.java档案

中

@Controller
public class RoleController {

@RequestMapping(value = "/masterRole")
public ModelAndView about() {
    RoleDAO dao = new RoleDAOImpl();
    List<Role> list = dao.list();
    ModelAndView model = new ModelAndView();
    model.addObject("list",list);
    model.setViewName("roleTile");
    return model;
     }
}

在tiles.xml档案

中

  <definition name="roleTile" extends="base.definition" >
    <put-attribute name="title" value="DAM Role Master" />
    <put-attribute name="body" value="/WEB-INF/pages/viewRole.jsp" />
    <put-attribute name="menuselection" value="master" />
</definition>

在viewRole.jsp档案

中

 <%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
 <%@ taglib prefix="datatables" uri="http://github.com/dandelion/datatables" %>

 <datatables:table id="roles" data="${list}" row="role" cssClass="table table-striped">
<datatables:column title="Id">
    <c:out value="${role.roleId}"></c:out>
</datatables:column>
<datatables:column title="Role">
    <c:out value="${role.role}"></c:out>
</datatables:column>
 </datatables:table>

我收到以下错误

我是Datatables的新手。请帮帮我。

还邀请链接与Spring 4一起使用hibernate和tiles逐步集成Datatbles。

Answer 1

错误表示datatables

的web.xml中缺少配置

第1步：在web.xml

<!-- Dandelion-Datatables servlet definition -->
<servlet>
    <servlet-name>datatablesController</servlet-name>
    <servlet-class>com.github.dandelion.datatables.extras.servlet2.servlet.DatatablesServlet</servlet-class>
</servlet>
<servlet-mapping>
    <servlet-name>datatablesController</servlet-name>
    <url-pattern>/datatablesController/*</url-pattern>
</servlet-mapping>

<!-- Dandelion servlet definition and mapping -->
<servlet>
  <servlet-name>dandelionServlet</servlet-name>
  <servlet-class>com.github.dandelion.core.web.DandelionServlet</servlet-class>
  <load-on-startup>2</load-on-startup>
</servlet>
<servlet-mapping>
  <servlet-name>dandelionServlet</servlet-name>
  <url-pattern>/dandelion-assets/*</url-pattern>
</servlet-mapping>

  <!-- Dandelion filter definition and mapping -->
 <filter>
   <filter-name>dandelionFilter</filter-name>
   <filter-class>com.github.dandelion.core.web.DandelionFilter</filter-class>
 </filter>
 <filter-mapping>
   <filter-name>dandelionFilter</filter-name>
   <url-pattern>/*</url-pattern>
</filter-mapping>

第2步：添加必需的jar文件

公地BeanUtils的-1.9.1.jar
蒲公英核心0.10.0.jar
数据表芯，0.10.0.jar
数据表，JSP的0.10.0.jar
数据表，servlet2-0.9.3.jar
ehcache的核心 - 2.6.9.jar
杰克逊的注解-2.2.3.jar
杰克逊核心2.2.3.jar
杰克逊 - 数据绑定-2.2.3.jar
JSON-简单1.1.1.jar
JSTL-api.jar文件
JSTL-impl.jar中
的log4j-1.2.16.jar

其他罐子：春季罐子+瓷砖罐子+ hibernate罐子

注意：我根据项目需要调整了罐子，你可以根据需要添加罐子。

Answer 2

您的问题可能来自web.xml中缺少某些声明。已在forum中报告，并且v0.10.1中将提供修复程序，以警告用户有关缺少声明的内容。

关于 datatables-servlet2 额外的一点说明。从v0.10.0开始，它不再存在。所以我建议你删除它并避免0.9.3和0.10.0可能的依赖问题。

web.xml中的新声明如下：

<!-- Dandelion-Datatables filter used for basic export -->
<filter>
    <filter-name>datatables</filter-name>
    <filter-class>com.github.dandelion.datatables.core.web.filter.DatatablesFilter</filter-class>
</filter>
<filter-mapping>
    <filter-name>datatables</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

文档的export section已更新，以反映最后的更改。
