spring-boot 使用原生Servlet

spring-boot 使用原生Servlet

配置一

@WebServlet(urlPatterns = "/testServlet/*")
public class TestServlet extends HttpServlet {

	private static final long serialVersionUID = -7866686514340118523L;

	@Override
	protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
		this.doPost(req, resp);
	}

	@Override
	protected void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
		resp.setCharacterEncoding("UTF-8");
		resp.setContentType("application/json; charset=utf-8");
		String jsonStr = "{\"name\":\"fly\",\"type\":\"虫子\"}";
		PrintWriter out = null;
		try {
			out = resp.getWriter();
			out.write(jsonStr);
		} catch (IOException e) {
			e.printStackTrace();
		} finally {
			if (out != null) {
				out.close();
			}
		}
	}

}

配置二

public class Test2Servlet extends HttpServlet {

	private static final long serialVersionUID = -5327348304390633663L;

	@Override
	protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
		this.doPost(req, resp);
	}

	@Override
	protected void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
		resp.setCharacterEncoding("UTF-8");
		resp.setContentType("application/json; charset=utf-8");
		String jsonStr = "{\"name\":\"fly\",\"type\":\"虫子1\"}";
		PrintWriter out = null;
		try {
			out = resp.getWriter();
			out.write(jsonStr);
		} catch (IOException e) {
			e.printStackTrace();
		} finally {
			if (out != null) {
				out.close();
			}
		}
	}

}

使用配置文件@Bean注入方式

@SpringBootApplication
@ServletComponentScan
@Import(value={SpringUtil.class})
public class App {
	
    @Bean
    public ServletRegistrationBean MyServlet1(){
        return new ServletRegistrationBean(new Test2Servlet(),"/test2Servlet/*");
    }

    public static void main(String[] args) {
        Class<?>[] c = {App.class};
    	SpringApplication.run(c, args);
    }
}
