数据绑定不使用弹簧taglib [英] Data binding without using spring taglib

问题描述

我的html是在不使用spring taglib的情况下构建的，现在我想将表单的参数绑定到控制器中的对象。

My html is built without using the spring taglib and now I'd like to bind the parameters of the form to a object in my controller.

目前我的表单看起来像这样

Currently my form looks like this

<form>
<input type="text" name="frAccUserMgmt.userName"/>
<input type="password" name="frAccUserMgmt.userPwd"/>
</form>

我的对象的相关部分是

Class FrAccUserMgmt {
    private String userName;
    private Strint userPwd;
    // getter and setter
}

我的控制器是

@RequestMapping("login")
Public ModelAndView doLogin(FrAccUserMgmt frAccUserMgmt) {
    //code
}

我如何去绑定它呢？目前绑定不会发生。我只是在我的代码中找到一个空的对象。

How do I go about binding it. Currently the binding doesn't happen. I just get an empty object in my code.

推荐答案

你可以尝试包括 BindingResult 类中的方法签名，然后查看是否有任何绑定错误：

You could try including the BindingResult class in the method signature and then see if there are any binding errors:

@RequestMapping("login")
Public ModelAndView doLogin(FrAccUserMgmt frAccUserMgmt, BindingResult result) {
    if (result.hasErrors()) {
        logger.warn("BindingResult errors: " + result.toString());
    }
    //code
}

删除 frAccUserMgmt 表单域名中的部分。 Spring将根据命令对象中定义的getter和setter自动找到命令对象来绑定请求参数。

Remove the frAccUserMgmt part from the form field names. Spring will automatically find the command object to bind the request parameters based on the getters and setters defined in the command object.
