- 創建java靜態方法
package demo;
import java.util.Map;
/**

*/
public class Demo {
public static String demo(){
String str = "11111111111";
return str;
}
}
- 在WEB-INF目錄下創建.tld文件，我這裏是sdk.tld
<?xml version="1.0" encoding="UTF-8"?>
<taglib xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee/web-jsptaglibrary_2_0.xsd"
version="2.0">
<tlib-version>1.2</tlib-version>
<short-name>sdk</short-name>
<function>
<name>demo</name>
<function-class>demo.Demo</function-class>
<function-signature>java.lang.String demo()</function-signature>
</function>
</taglib>3.在web.xml中配置sdk.tld
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
version="3.1">
<jsp-config>
<taglib>
<taglib-uri>Demo</taglib-uri>
<taglib-location>/WEB-INF/sdk.tld</taglib-location>
</taglib>
</jsp-config>
</web-app>4.編寫jsp文件，並且引入sdk.tld

5.運行項目後將會看到如下結果
