先创建javaee 看另一篇文章 javaee 创建web项目
添加springmvc的依赖
- 打开pom.xml
-
<dependency><groupId>jakarta.servlet</groupId><artifactId>jakarta.servlet-api</artifactId><version>5.0.0</version><scope>provided</scope></dependency><dependency><groupId>org.junit.jupiter</groupId><artifactId>junit-jupiter-api</artifactId><version>${junit.version}</version><scope>test</scope></dependency><dependency><groupId>org.junit.jupiter</groupId><artifactId>junit-jupiter-engine</artifactId><version>${junit.version}</version><scope>test</scope></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-webmvc</artifactId><version>6.0.7</version></dependency>
</dependencies>
- 报错红色的话 右面选中m然后刷新一下依赖
配置SpringMvc控制器用来处理请求
- 新建一个Controller文件夹，然后在下面新建一个UserController
package Controller;import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.bind.annotation.RestController;/**
* @author admin
*/
@Controller
@RestController("user")
public class userController {@RequestMapping(value = "/user")@ResponseBodypublic String getUser(){return "hello";}
}
添加springmvc配置类
新建包Config 配置类在此包下新建java类
package Config;import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;/**
* @author admin
*/
//创建Springmvc的配置类，并加载到ioc容器中，
//加载contorller对应的bean
@Configuration
@ComponentScan(basePackages = {"Controller"})
public class SpringMvcConfig {}
初始化Springmvc环境
package Config;import org.springframework.web.context.WebApplicationContext;
import org.springframework.web.context.support.AnnotationConfigWebApplicationContext;
import org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer;
import org.springframework.web.servlet.support.AbstractDispatcherServletInitializer;//定义一个servlet容器启动配置类，加载到Spring配置
public class SpringMvcInitConfig extends AbstractDispatcherServletInitializer {
// 初始化Springmvc环境@Overrideprotected WebApplicationContext createServletApplicationContext() {AnnotationConfigWebApplicationContext acwac = new AnnotationConfigWebApplicationContext();acwac.register(SpringMvcconfig.class);return acwac;}
//配置Mapping路径为"/"，代表所有接口接收@Overrideprotected String[] getServletMappings() {return new String[]{"/"};}//初始化spring 环境@Overrideprotected WebApplicationContext createRootApplicationContext() {return null;}
}
最后运行接口就可以了
