下拉框左编码右名称获取数据

//获取数据

List<Declarant> list = this.decParamLogic.findDeclarants(request);

//ItemProperty是code name 类
List<ItemProperty> propertys = new ArrayList();
if (list != null) {
for (Declarant declarant : list) {
propertys.add(new ItemProperty(declarant.getCode(), declarant.getName()));
}
}

//设置成下拉框样式
tfDeclarant.setModel(new DefaultComboBoxModel(propertys.toArray()));

//值转换器方法，解决字符串保存问题

this.tfDeclarant.setConvert(new ItemPropertyValueConvert(new DefaultComboBoxModel(propertys.toArray())));
