先编写模板页面：
blog.ftl：
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Insert title here</title>
</head>
<body>
博客id:${id}
</body>
</html>
helloWorld.ftl：
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Insert title here</title>
</head>
<body>
show: ${message}
</body>
</html>
query.ftl：
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Insert title here</title>
</head>
<body>
q: ${q}
</body>
</html>
编写BlogController控制器：
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.servlet.ModelAndView;
@Controller
@RequestMapping("/blog")
public class BlogController {
@RequestMapping("/{id}")
public ModelAndView show(@PathVariable("id") Integer id){
ModelAndView mav=new ModelAndView();
mav.addObject("id", id);
mav.setViewName("blog");
return mav;
}
@RequestMapping("/query")
public ModelAndView query(@RequestParam(value="q",required=false)String q){
ModelAndView mav=new ModelAndView();
mav.addObject("q", q);
mav.setViewName("query");
return mav;
}
}
访问链接：http://localhost:8888/HelloWorld/blog/1
http://localhost:8888/HelloWorld/blog/query?q=666
编写HelloWorldAjaxController控制器：
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
@RequestMapping("/ajax")
public class HelloWorldAjaxController {
@RequestMapping("/hello")
public String say(){
return "{'message1':'SpringBoot大爷你好','message2','Spring大爷你好2'}";
}
}
访问链接：http://localhost:8888/HelloWorld/ajax/hello
编写HelloWorldFreemarkerController控制器：
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
@Controller
@RequestMapping("/freemarker")
public class HelloWorldFreemarkerController {
@RequestMapping("/say")
public ModelAndView say(){
ModelAndView mav=new ModelAndView();
mav.addObject("message", "springboot大爷你好！");
mav.setViewName("helloWorld");
return mav;
}
}
