Question

我正在使用JSF（PrimeFaces）/ EJB / JPA和MySQL数据库。我想要做的是在用户成功引入数据库时显示XHTML BODY的顶部“用户已成功添加到数据库”信息消息。我知道我可以使用h：消息但是，然后验证错误消息`显示在正文的顶部，我希望错误消息显示在输入字段下方。我怎么能这样做？

Facelet代码

 <h:body>
<h:messages  errorStyle="color: red" infoStyle="color: green" layout="table"/>`<!--WRONG-->

    <p:inputText id="name" required="true" value="#{usersManagedBean.username}" requiredMessage="requiered field">              
              <f:validator validatorId="validators.NameValidator"/>
    </p:inputText>
    <p:watermark for="name" value="User" />
    <p:message for="name" />


    <p:inputText id="age" required="true" value="#{usersManagedBean.username}" requiredMessage="requiered field">              
              <f:validator validatorId="validators.AgeValidator"/>
    </p:inputText>
    <p:watermark for="age" value="Age" />
    <p:message for="age" />


    <p:commandButton value="Save user" action="#{usersManagedBean.saveUser}" ajax="false" />

    </h:body>

托管Bean代码

//imports

@Named(value = "usersManagedBean")
@SessionScoped
public class UsersManagedBean implements Serializable 
{

String username;
int  userage;

@PostConstruct
    public void init()
    {
        username="";
    userage=0;
    }

//Getters and Setters

public void saveUser()
{
    User eUser = new Users();

    eUser.setName(username);
    eUser.setAge(userage);

    ejbUsersDAO.create(eUser); //DAO
    addSuccessMessage("User was successfully added to database");

}

 public static void addSuccessMessage(String msg) 
{
        FacesMessage facesMsg = new FacesMessage(FacesMessage.SEVERITY_INFO, msg, msg);
        FacesContext fc = FacesContext.getCurrentInstance();
        fc.addMessage("successInfo", facesMsg);
}

}

Answer 1

尝试在globalOnly="true"中设置<h:messages>属性，并将addSuccessMessage更改为

fc.addMessage(null, facesMsg);

在输入字段下方显示面部消息
