Struts2中的多个提交按钮问题

发布于 2024-10-10 02:44:00 字数 592 浏览 10 评论 0原文

尝试在 struts2 应用程序中的单个表单中使用多个提交按钮，但无法工作。这是我使用的jsp代码，

<tr>
<td class="button"><input type="submit" value="Import"
        name="destinationImport" class="button"></td>
    <td class="button"><input type="submit" value="Export"
        name="destinationExport" class="button"></td>
</tr>

这里是java部分

private boolean destinationImport;
private boolean destinationExport;
//and the respective setters and getters

，但我确信Struts2类型转换器在将字符串值转换为布尔值时遇到问题有人知道如何实现这一目标吗？

提前致谢

方法： getDestinationExport / setDestinationExport 应该处理字符串，因为您的值：“Export”和“Import”不能直接转换为布尔类型。
如果需要通过内部规则进行转换，请将相应的代码放在setDestinationExport中。像这样的东西：

 public void setDestinationExport(String arg){
     destinationExport = "Export".equals(arg);
     destinationImport = "Import".equals(arg);
 }

Methods : getDestinationExport / setDestinationExport should deal with String, since your values: "Export" and "Import" aren't convertible directly to boolean type.
If you need convert it by internal rule, place corresponding code inside setDestinationExport. Something like that:

 public void setDestinationExport(String arg){
     destinationExport = "Export".equals(arg);
     destinationImport = "Import".equals(arg);
 }

这种方式应该有效

private boolean destinationImport = false;
private boolean destinationExport = false;

public void setDestinationImport(boolean destinationImport) {
  this.destinationImport = true;
}

public void setDestinationExport(boolean destinationExport) {
  this.destinationExport = true;
}

参考：

This way should works

private boolean destinationImport = false;
private boolean destinationExport = false;

public void setDestinationImport(boolean destinationImport) {
  this.destinationImport = true;
}

public void setDestinationExport(boolean destinationExport) {
  this.destinationExport = true;
}
