Spingmvc using Bindingresult to return error messages to the page

The error message is returned to the page using Bindingresult in SPINGMVC.

In Actionfrom:

private String name;

private String password;

Get ()/set () ....

In the JSP:

<form:form id= "T51000actionform" name= "T51000actionform" modelattribute= "T51000actionform" method= "POST" >

Name: <form:input type= "text" path= "name" size= "" maxlength= "" cssstyle= "ime-mode:active;" />

<form:errors path= "name" cssclass= "Errorclass" ></form:errors>

Password: <form:input type= "text" path= "password" size= "" maxlength= "" cssstyle= "ime-mode:active;" />

<form:errors path= "Password" cssclass= "Errorclass" ></form:errors>

</from>

The property value of path is the same as that of the variable in Actionform, so that you can find out which property is wrong in the form

Background controller

@RequestMapping ("/t51000torokuevaction")
Publicstring Gettoroku (@ModelAttribute ("T51000actionform") T51000actionform t51000actionform) {

if (Name.equal ("")) {

Result.rejectvalue ("name", Errorcode,,defaultmessage);

}

}

This will display the error message in the location of the property that corresponds to the page.
