除了request.getparameter外，还有以下方法

1，model map中保存key,value

如：

@RequestMapping("/getAgent")
public String getAgentById(HttpServletRequest req,Map<String,Object> map){
log.info("进入getAgentById");
Agent agent=agentService.getAgentById("123");
log.info(agent.toString());
req.setAttribute("name", agent.getName());
req.setAttribute("id", agent.getAgentId());
map.put("agentt", agent);
//mo.addAttribute("agen", agent);
//mo.addAttribute("greetings", "I came from Model not ModelAttribute");
return "getResult";
}

jsp页面如下：

<body>
hello world!
<%--
<c:forEach items="${agent}" var="p">
agentId:${p.agentId}
companyCode:${p.companyCode}
loginName:${p.loginName}
name:${p.name}
</c:forEach>
--%>

<c:out value="${greetings}" />

${greetings}

${agentt}
${agentt.name}

显示结果如下：

hello world!

Agent [agentId=123, companyCode=456, loginName=zzz, name=周周周]

周周周
