如何在不同的消息组件上添加 Faceslets 消息？

Question

我想在不同的消息组件上有不同的消息，但不幸的是消息总是显示在两个消息组件上。

TestFaces.java

import javax.faces.application.FacesMessage;
import javax.faces.context.FacesContext;

import org.apache.logging.log4j.LogManager;
import org.apache.logging.log4j.Logger;

@javax.enterprise.context.RequestScoped
@javax.inject.Named
public class TestFaces implements java.io.Serializable {
    static final long serialVersionUID = 1L;
    static final Logger logger = LogManager.getLogger();

    public String callMsg001() {
        FacesContext.getCurrentInstance().addMessage("msg001",
                new FacesMessage(FacesMessage.SEVERITY_INFO, "This is msg001", null));

        return null;
    }
    
    public String callMsg002() {
        FacesContext.getCurrentInstance().addMessage("msg002",
                new FacesMessage(FacesMessage.SEVERITY_INFO, "This is msg002", null));

        return null;
    }

}

        <h:commandButton
            value="Trigger msg001"
            action="${testFaces.callMsg001()}">
        </h:commandButton>
        <h:commandButton
            value="Trigger msg002"
            action="${testFaces.callMsg002()}">
        </h:commandButton>
    </h:form>

Output

我想在不同的消息组件上有不同的消息。

工作示例如下。

TestFaces.java

import javax.faces.application.FacesMessage;
import javax.faces.context.FacesContext;

@javax.enterprise.context.RequestScoped
@javax.inject.Named
public class TestFaces implements java.io.Serializable {
    static final long serialVersionUID = 1L;

    public String callCmd001() {
        FacesContext.getCurrentInstance().addMessage(null,
                new FacesMessage(FacesMessage.SEVERITY_INFO, "This is global cmd001", null));
        
        FacesContext.getCurrentInstance().addMessage("form001:cmd001",
                new FacesMessage(FacesMessage.SEVERITY_INFO, "This is cmd001", null));

        return null;
    }

    public String callCmd002() {
        FacesContext.getCurrentInstance().addMessage(null,
                new FacesMessage(FacesMessage.SEVERITY_INFO, "This is global cmd002", null));
        
        FacesContext.getCurrentInstance().addMessage("form001:cmd002",
                new FacesMessage(FacesMessage.SEVERITY_INFO, "This is cmd002", null));

        return null;
    }

}
