我发现了很多问题“如何在新窗口中打开表单结果” https://stackoverflow.com/search?q=spring%20form%20new%20window，但我面临着相反的问题。
我有表格：
<form:form method="post" commandName="search">
...
<input type="submit" value="Search" />
</form>
然后我有带有处理方法的控制器
@RequestMapping(value = "/search.form", method = RequestMethod.POST)
public String submit( @Valid final SearchObject searchObject, final BindingResult bindingResult ) {
if ( bindingResult.hasErrors() ) return "forms/search";
return "redirect:/A/result.form";
}
一切正常，除了结果是在新窗口/选项卡中打开之外。
我找到并正在工作的解决方案是添加目标属性：
<form:form method="post" commandName="search" target="_self">
But _self是默认的 AFAIK。
我想知道为什么会发生这种情况。
我检查了生成的 HTML，在我看来没问题：
<form id="search" action="/myApp/A/search.form" method="post">

edit 2为 result.form 添加了方法
@RequestMapping(value = "/result.form", method = RequestMethod.GET)
public String result() {
return "forms/result";
}
我的控制器类开始于：
@Controller
@RequestMapping(value = "/A")
public class AController {
