我有表单person.jsp:

<%@taglib uri="http://www.springframework.org/tags/form" prefix="form"%>
<html>
<head>
<title>Person form</title>
</head>
<body>
    <form method="POST" action="addPerson.html">

        <form:label path="name"></form:label>

        <form:label path="lastName"></form:label>

        <form:label path="age"></form:label>

        <input type="submit" value="Add Contact" />

    </form>


</body>
</html>

和控制器：

@Controller
public class FormControler {

    @RequestMapping(value="/addPerson", method = RequestMethod.POST)
    private void contrler(@ModelAttribute("person")Person person, BindingResult result) {

        System.out.println("Name "+person.getName());

    }
    @RequestMapping(value="/person", method = RequestMethod.GET)
    public ModelAndView showContscts() {

        return new ModelAndView("person", "command", new Person());
    }

}

还有Person.java:

public class Person {

    private String name;
    private String lastName;
    private String age;

    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public String getLastName() {
        return lastName;
    }
    public void setLastName(String lastName) {
        this.lastName = lastName;
    }
    public String getAge() {
        return age;
    }
    public void setAge(String age) {
        this.age = age;
    }


}

还有index 网站和&lt;a href:

<!DOCTYPE html>
<%@ taglib prefix="form" uri="http://www.springframework.org/tags/form"%>
<html>
<body>

    <a href="person">Person</a>

</body>
</

【问题讨论】：

    标签： java model-view-controller spring-mvc


    【解决方案1】：

    您必须通过这种方式将表单绑定到模型：

    <form:form method="POST" action="addPerson.html" modelAttribute="person">
    <form:label path="name"></form:label>
    <form:label path="lastName"></form:label>
    <form:label path="age"></form:label>
    <input type="submit" value="Add Contact" />
</form: form>

    【讨论】：

    • 我编辑了表单，但我仍然看到同样的异常。
    • 只是为了确认您确实使用了form:form 标签而不是直接使用form 对吗？
    • 是的，我改成form:form并添加modelAttribute。
    【解决方案2】：

    你有你在 jsp 文件中的表格：假设 jsp 名称是 person.jsp

    <form:form method="POST" action="addPerson" modelAttribute="person">
    <form:label path="name"></form:label>
    <form:label path="lastName"></form:label>
    <form:label path="age"></form:label>
    <input type="submit" value="Add Contact" />
</form: form>

    现在加载 person.jsp 的操作方法应该是这样的：

    @Controller
public class FormControler {

    @RequestMapping(value="/addPerson", method = RequestMethod.POST)
    private void contrler(@ModelAttribute("person")Person person, BindingResult result)  { 
        System.out.println("Name "+person.getName());
    }

    // Your this method is going to show pseron jsp page
    // dont return model and view, instead try this

    @RequestMapping(value="/person", method = RequestMethod.GET)
    public String showContacts(Model model) {
        // your jsp demands Person.java as modelAttribute
        // add that POJO in model and send along with your jsp

        model.addAttribute("person", new Pseron()); // this attribute name should be same as it is in modelAttribute of jsp form
        return "person";
    }
}

    试试这个。

    【解决方案3】：

    我使用本主题中的建议解决了我的问题，但我也将 ModelAndView("person", "command", new Person()) 中的名称从 command 更改为 person。
