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</br>
</span><span style="color: #0000ff;">protected</span><span style="color: #000000;"> SpringApplicationBuilder configure(SpringApplicationBuilder application) {</br>
    </span><span style="color: #0000ff;">return</span> application.sources(Application.<span style="color: #0000ff;">class</span><span style="color: #000000;">);</br>
}</br></br>

</span><span style="color: #0000ff;">public</span> <span style="color: #0000ff;">static</span> <span style="color: #0000ff;">void</span> main(String[] args) <span style="color: #0000ff;">throws</span><span style="color: #000000;"> Exception {</br>
    SpringApplication.run(Application.</span><span style="color: #0000ff;">class</span><span style="color: #000000;">, args);</br>
}</br></br>

}

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(</span>"${application.message}"<span style="color: #000000;">)</br>
</span><span style="color: #0000ff;">private</span><span style="color: #000000;"> String message;</br></br>


@GetMapping(</span>"/welcome"<span style="color: #000000;">)</br>
</span><span style="color: #0000ff;">public</span> String welcome(Map&lt;String, Object&gt;<span style="color: #000000;"> model) {</br>
    model.put(</span>"time", <span style="color: #0000ff;">new</span><span style="color: #000000;"> Date().getTime());</br>
    model.put(</span>"message", <span style="color: #0000ff;">this</span><span style="color: #000000;">.message);</br>
    </span><span style="color: #0000ff;">return</span> "welcome"<span style="color: #000000;">;</br>
}</br></br>

@GetMapping(</span>"/test"<span style="color: #000000;">)</br>
</span><span style="color: #0000ff;">public</span><span style="color: #000000;"> String test(){</br>
    </span><span style="color: #0000ff;">return</span> "test"<span style="color: #000000;">;</br>
}</br></br>

}

pom.xml 文件的所有配置:
