springboot 配置jsp支持

springboot默认并不支持jsp模板，所以需要配置。

下面是一个可以运行的例子：

首先配置属性文件:

spring.http.encoding.force=true
spring.http.encoding.charset=UTF-8
spring.http.encoding.enabled=true
server.tomcat.uri-encoding=UTF-8

server.port=8080

spring.mvc.view.prefix: /WEB-INF/jsp/
spring.mvc.view.suffix: .jsp
application.message: Hello world

然后配置启动类:

package sample.jsp;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.support.SpringBootServletInitializer;

@SpringBootApplication
public class Application extends SpringBootServletInitializer {

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(Application.class);
    }

    public static void main(String[] args) throws Exception {
        SpringApplication.run(Application.class, args);
    }

}

最后写一下控制层:

package sample.jsp;

import java.util.Date;
import java.util.Map;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class WelcomeController {

    @Value("${application.message}")
    private String message;

    @GetMapping("/welcome")
    public String welcome(Map<String, Object> model) {
        model.put("time", new Date().getTime());
        model.put("message", this.message);
        return "welcome";
    }

    @GetMapping("/test")
    public String test(){
        return "test";
    }

}

pom.xml 文件的所有配置:
