使用 Spring WebMvc 的时候,经常返回的内容包括 json 和 xml 和视图,下面给出直接在 controller 中返回文本的示例。

JiangBoApplication
package jiangbo.spring.boot;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class JiangBoApplication {
public static void main(String[] args) {
SpringApplication.run(JiangBoApplication.class, args);
}
}
HelloController
package jiangbo.spring.boot.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.ResponseBody;
@Controller
public class HelloController {
@GetMapping("/hello")
@ResponseBody
public String hello(String name) {
return "hello: " + name;
}
}
浏览器访问
使用 SpringBoot 的方式启动项目,在浏览器端访问 http://localhost:8080/hello?name=张三 ,查看浏览是否显示:
hello: 张三
因为 SpringBoot 帮自动配置了一些类型转换,所以即使是中文也不会出现乱码。
