第一步:创建一个BaseController。
public class BaseController {
/**
* 重写方法
*/
@InitBinder
public void initBinder(WebDataBinder binder) {
binder.registerCustomEditor(String.class, new StringEscapeEditor(true, false));
}
第二步,创建所需的StringEscapeEditor类
import org.springframework.web.util.HtmlUtils;
import org.springframework.web.util.JavaScriptUtils;
import java.beans.PropertyEditorSupport;
/**
* 转义工具类(主要针对xss攻击)
*/
public class StringEscapeEditor extends PropertyEditorSupport {
private boolean escapeHTML;// 编码HTML
private boolean escapeJavaScript;// 编码javascript
public StringEscapeEditor() {
super();
}
public StringEscapeEditor(boolean escapeHTML, boolean escapeJavaScript) {
super();
this.escapeHTML = escapeHTML;
this.escapeJavaScript = escapeJavaScript;
}
@Override
public String getAsText() {
Object value = getValue();
return value != null ? value.toString() : "";
}
@Override
public void setAsText(String text) throws IllegalArgumentException {
if (text == null) {
setValue(null);
} else {
String value = text;
if (escapeHTML) {
value = HtmlUtils.htmlEscape(value);
}
if (escapeJavaScript) {
value = JavaScriptUtils.javaScriptEscape(value);
}
setValue(value);
}
}
}
第三步: 其他Controller 继承 BaseController
知识点以及注意:
1.主要是使用 HtmlUtils.htmlEscape(value)进行转义的.
2.注意BaseController 上没有@controller注解.
