今天完成了SpringMVC-快速返回逻辑视图，可以看作是springmvc一个非常基础的demo
效果:
代码:
index.jsp
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
<title>Title</title>
</head>
<body>
<font color="red">${data}</font>
</body>
</html>
package com.aurora.config;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.config.annotation.ViewResolverRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;
@Configuration
@ComponentScan("com.aurora.jsp")
@EnableWebMvc
public class MvcConfig implements WebMvcConfigurer {
@Override
public void configureViewResolvers(ViewResolverRegistry registry) {
//可以快速添加前后缀
registry.jsp("/WEB-INF/views/",".jsp");
}
}
package com.aurora.config;
import org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer;
public class SpringMVCInit extends AbstractAnnotationConfigDispatcherServletInitializer {
@Override
protected Class<?>[] getRootConfigClasses() {
return new Class[0];
}
@Override
protected Class<?>[] getServletConfigClasses() {
return new Class[]{MvcConfig.class};
}
@Override
protected String[] getServletMappings() {
return new String[]{"/"};
}
}
package com.aurora.jsp;
import jakarta.servlet.http.HttpServletRequest;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
@RequestMapping("jsp")
public class JspController {
/**
* TODO:快速查找视图
* 1.方法的返回值是字符串类型
* 2.不能添加@ResponseBody，直接返回字符串给浏览器，不找视图，不走视图解析器
* 3.返回值 对应中间的视图名称即可
*/
@GetMapping("index")
public String index(HttpServletRequest request){
request.setAttribute("data","hello jsp!!hello Aurora!!");
System.out.println("JspController.index");
return "index";
}
}
