Spring的command属性的绑定

开发当中发现extjs的checkbox的value是on off。But 我们设计的数据库中使用的是int。spring中原先定义的customEditor都不好使了。只有自己搞一个

import org.springframework.beans.propertyeditors.PropertiesEditor;
import org.springframework.util.StringUtils;

public class CustomExtjsBoolenEditor extends PropertiesEditor {
	private final boolean allowEmpty;
	
	private final String trueString="on";
//	private final String falseString="off";

	public CustomExtjsBoolenEditor(boolean allowEmpty) {
		this.allowEmpty = allowEmpty;
	}

	/**
	 * Parse the Number from the given text, using the specified NumberFormat.
	 */
	public void setAsText(String text) throws IllegalArgumentException {
		if (this.allowEmpty && !StringUtils.hasText(text)) {
			// Treat empty String as null value.
			setValue(null);
		} else if (trueString.equalsIgnoreCase(text)) {
			// Use given NumberFormat for parsing text.
			setValue(1);
		} else {
			// Use default valueOf methods for parsing text.
			setValue(0);
		}
	}



	/**
	 * Format the Number as String, using the specified NumberFormat.
	 */
	public String getAsText() {
		Object value = getValue();
		if (value == null) {
			return "";
		}
		
			return value.toString();
	
	}
}

inbinder中的代码

binder.registerCustomEditor(Integer.class, "属性名", new CustomExtjsBoolenEditor(true));
