Question

我制作了一个表格，将一些数据添加到我的数据库中。这是我的html编码。单击“提交”按钮时，go()方法不会触发。这是为什么？

<form jsf:id="formAddDesignation">
                            <br/>
                            <div class="row">
                                <div class="col-xs-4">Designation Name</div>
                                <div class="col-xs-6">
                                    <input type="text" required="true" jsf:value="#{designationBean.designationName}" placeholder="Designation name" jsf:id="designationName" class="form-control" />
                                </div>
                            </div>
                            <br/>
                            <div class="row">
                                <div class="col-xs-4">Designation Description</div>
                                <div class="col-xs-6">
                                    <textarea class="form-control" jsf:value="#{designationBean.designationDescription}" placeholder="Designation description"></textarea>
                                </div>
                            </div>
                            <br/>
                            <div class="row" style="padding-right:  54px">
                                <button type="submit" jsf:id="btnAddDesignation" jsf:action="#{designationBean.go()}" class="btn btn-default col-xs-5 col-xs-offset-8 pull-right">Login
                                    <f:ajax  execute="formAddDesignation" render="logs" />
                                </button>
                            </div>

                        </form>

托管Bean（CDI）

@Named(value = "designationBean")
@RequestScoped
public class DesignationBean implements Serializable {

    private String designationName;

    private String designationDescription;

    private Boolean status;


    public DesignationBean() {
        System.out.println("dddeeeee");
    }

    @PostConstruct
    public void init() {
        status = false;
        System.out.println("ddddddddd");
        designationName = "dddd";

    }

    public String getDesignationName() {
        return designationName;
    }

    public void setDesignationName(String designationName) {
        this.designationName = designationName;
    }

    public String getDesignationDescription() {
        return designationDescription;
    }

    public void setDesignationDescription(String designationDescription) {
        this.designationDescription = designationDescription;
    }

    public Boolean getStatus() {
        return status;
    }

    public void setStatus(Boolean status) {
        this.status = status;
        System.out.println("status");
    }

    public String go(){
        System.out.println("Method is clicked");
        return "clicked";
    }

}

只尝试＆＃34; designationBean.go＆＃34;没有括号。据我记忆，你不要括号！

表单提交时不会触发JSF托管bean方法
