geList", pageList);
// Array数组
PageBO[] pageArr = new PageBO[]{new PageBO(6,"第六页"),new PageBO(7,"第七页")} ;
modelAndView.addObject("pageArr", pageArr);
modelAndView.setViewName("/page-view");
return modelAndView ;
}
}
页面解析：分别解析了普通参数，实体对象，集合容器，数组容器等几种数据模型；
<div style="text-align: center">
<hr/>
<h5>普通参数解析</h5>
姓名：<span th:text="${name}"></span>
时间：<span th:text="${time}"></span>
<hr/>
<h5>对象模型解析</h5>
整形：<span th:text="${page.getKey()}"></span>
字符：<span th:text="${page.getValue()}"></span>
<hr/>
<h5>集合容器解析</h5>
<table style="margin:0 auto;width: 200px">
<tr>
<th>Key</th>
<th>Value</th>
</tr>
<tr th:each="page:${pageList}">
<td th:text="${page.getKey()}"></td>
<td th:text="${page.getValue()}"></td>
</tr>
</table>
<hr/>
<h5>数组容器解析</h5>
<table style="margin:0 auto;width: 200px">
<tr>
<th>Key</th>
<th>Value</th>
</tr>
<tr th:each="page:${pageArr}">
<td th:text="${page.getKey()}"></td>
<td th:text="${page.getValue()}"></td>
</tr>
</table>
<hr/>
</div>

四、拦截器
1、拦截器定义
通过实现HandlerInterceptor接口，完成对两个拦截器的自定义，请求在访问服务时，必须通过两个拦截器的校验；
/**
* 拦截器一
*/
public class HeadInterceptor implements HandlerInterceptor {
private static final Logger log = LoggerFactory.getLogger(HeadInterceptor.class);
@Override
public boolean preHandle(HttpServletRequest request, HttpServletResponse response,
Object handler) throws Exception {
log.info("HeadInterceptor:preHandle");
Iterator<String> headNames = request.getHeaderNames().asIterator();
log.info("request-header");
while (headNames.hasNext()){
String headName = headNames.next();
String headValue = request.getHeader(headName);
System.out.println(headName+":"+headValue);
}
// 放开拦截
return true;
}
@Override
public void postHandle(HttpServletRequest request,HttpServletResponse response,
Object handler, ModelAndView modelAndView) throws Exception {
log.info("HeadInterceptor:postHandle");
}
@Override
public void afterCompletion(HttpServletRequest request,HttpServletResponse response,
Object handler, Exception e) throws Exception {
log.info("HeadInterceptor:afterCompletion");
}
}
/**
* 拦截器二
*/
public class BodyInterceptor implements HandlerInterceptor {
private static final Logger log = LoggerFactory.getLogger(BodyInterceptor.class);
@Override
public boolean preHandle(HttpServletRequest request,HttpServletResponse response,
Object handler) throws Exception {
log.info("BodyInterceptor:preHandle");
Iterator<String> paramNames = request.getParameterNames().asIterator();
log.info("request-param");
while (paramNames.hasNext()){
String paramName = paramNames.next();
String paramValue = request.ge
