傳送表單部分並收聽請求

Created: November-22, 2018

發出請求僅傳送表單的一部分。text1 值已設定，但不是 text2，如收聽者所述。

Bean.java

@ManagedBean
@ViewScoped
public class Bean {

    private String text1;

    private String text2;

    public String getText1() {
        return text1;
    }

    public void setText1(String text1) {
        this.text1 = text1;
    }

    public String getText2() {
        return text2;
    }

    public void setText2(String text2) {
        this.text2 = text2;
    }

    public void listener() {
        System.out.println("values: " + text1 + " " + text2);
    }

}
