The aop page is not applicable in the controller_html/css_WEB-ITnose
The problem is as follows
Today I found that aop cannot be used in the controller. It can be used if it is replaced with service. It can also be used with junit-test, but it cannot be placed under tomcat. I am confused. Got it! ! !
package com.tutor.normal.filter;import javax.annotation.Resource;import org.aspectj.lang.ProceedingJoinPoint;import org.aspectj.lang.annotation.After;import org.aspectj.lang.annotation.AfterReturning;import org.aspectj.lang.annotation.AfterThrowing;import org.aspectj.lang.annotation.Around;import org.aspectj.lang.annotation.Aspect;import org.aspectj.lang.annotation.Before;import org.aspectj.lang.annotation.Pointcut;import org.slf4j.Logger;import org.slf4j.LoggerFactory;import com.tutor.normal.service.ITutorUserService;/** * * @author jinghao.liang * */@Aspectpublic class TutorLoginAop { private static Logger log = LoggerFactory.getLogger(TutorLoginAop.class); @Resource(name = "tutorUserService") private ITutorUserService tutorUserService; @Pointcut("execution(* com.tutor.normal.controller..*.*(..))") private void anyMethod() { }// 定义一个切入点 @Before("anyMethod() && args(name)") public void doAccessCheck(String name) { System.out.println(name); System.out.println("前置通知"); } @AfterReturning("anyMethod()") public void doAfter() { System.out.println("后置通知"); } @After("anyMethod()") public void after() { System.out.println("最终通知"); } @AfterThrowing("anyMethod()") public void doAfterThrow() { System.out.println("例外通知"); } @Around("anyMethod()") public Object doBasicProfiling(ProceedingJoinPoint pjp) throws Throwable { System.out.println("进入环绕通知"); Object object = pjp.proceed();// 执行该方法 System.out.println("退出方法"); return object; }}
spring configuration, plus these two
<aop:aspectj-autoproxy proxy-target-class="true"/> <bean id="tutorLoginAop" class="com.tutor.normal.filter.TutorLoginAop" />
Nice, it’s obviously the same as the one on the Internet, what’s going on
After a day of troubleshooting, I finally found the problem. It turns out that the spring configuration should be written in springMVC, not in spring
What does it mean? Look at the configuration of my web.xml
<context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath*:spring/applicationContext.xml</param-value> </context-param> <!-- Spring MVC --> <servlet> <servlet-name>springMVC</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring/spring-servlet.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>springMVC</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping>
It turns out that I wrote the configuration in applicationContext.xml. Of course it won’t work. TVT needs to be written in spring-servlet.xml. . .

HTML defines the web structure, CSS is responsible for style and layout, and JavaScript gives dynamic interaction. The three perform their duties in web development and jointly build a colorful website.

HTML, CSS and JavaScript are the three pillars of web development. 1. HTML defines the web page structure and uses tags such as, etc. 2. CSS controls the web page style, using selectors and attributes such as color, font-size, etc. 3. JavaScript realizes dynamic effects and interaction, through event monitoring and DOM operations.

The roles of HTML, CSS and JavaScript in web development are: 1. HTML defines the web page structure, 2. CSS controls the web page style, and 3. JavaScript adds dynamic behavior. Together, they build the framework, aesthetics and interactivity of modern websites.

The future of HTML is full of infinite possibilities. 1) New features and standards will include more semantic tags and the popularity of WebComponents. 2) The web design trend will continue to develop towards responsive and accessible design. 3) Performance optimization will improve the user experience through responsive image loading and lazy loading technologies.

The future trends of HTML are semantics and web components, the future trends of CSS are CSS-in-JS and CSSHoudini, and the future trends of JavaScript are WebAssembly and Serverless. 1. HTML semantics improve accessibility and SEO effects, and Web components improve development efficiency, but attention should be paid to browser compatibility. 2. CSS-in-JS enhances style management flexibility but may increase file size. CSSHoudini allows direct operation of CSS rendering. 3.WebAssembly optimizes browser application performance but has a steep learning curve, and Serverless simplifies development but requires optimization of cold start problems.

The roles of HTML, CSS and JavaScript in web development are: HTML is responsible for content structure, CSS is responsible for style, and JavaScript is responsible for dynamic behavior. 1. HTML defines the web page structure and content through tags to ensure semantics. 2. CSS controls the web page style through selectors and attributes to make it beautiful and easy to read. 3. JavaScript controls web page behavior through scripts to achieve dynamic and interactive functions.

HTML is the cornerstone of building web page structure. 1. HTML defines the content structure and semantics, and uses, etc. tags. 2. Provide semantic markers, such as, etc., to improve SEO effect. 3. To realize user interaction through tags, pay attention to form verification. 4. Use advanced elements such as, combined with JavaScript to achieve dynamic effects. 5. Common errors include unclosed labels and unquoted attribute values, and verification tools are required. 6. Optimization strategies include reducing HTTP requests, compressing HTML, using semantic tags, etc.
