发生缘由

学习SpringMVC

运行环境

jdk版本：jdk-16.0.2
Idea版本：2021.2
电脑系统：win10

环境搭建

创建Maven项目。点击Maven项目创建时候的create from archetype，选择Maven里面的模板即可，选择org.apache.maven.archetypes:maven-archetype-webapp；
因为创建的目录结构不全，所以我们需要手动补全java文件夹。点击file-->Project Structure-->Moudles，在Moudles中选择刚刚创建的项目，看看src文件夹下面的main文件夹下面是否存在java文件夹。

如果没有则需要手动添加：右键main文件夹，选择new folder，在出现的方框中输入java。就会创建一个java文件夹。

将pom.xml中多余的内容删除掉，再添加SpringMVC需要的依赖。在pom.xml文件中添加SpringMVC所需要的jar包以及Tomcat运行所需要的插件，最后pom.xml文件内容如下：

<?xml version="1.0" encoding="UTF-8"?>

          <path>/</path>
        </configuration>
      </plugin>
    </plugins>
  </build>
</project>

创建配置类

package com.linxuan.config;

import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;

@Configuration
@ComponentScan("com.linxuan.controller")
public class SpringMvcConfig {
}

创建Controller类

package com.linxuan.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

@Controller
public class UserController {

    @RequestMapping("/save")
    // 设置返回数据为json
    @ResponseBody
    public String save() {
        System.out.println("user save...");
        return "{'info':'springmvc'}";
    }
}

使用配置类替换web.xml。将web.xml删除，换成ServletContainersInitConfig

package com.linxuan.config;

import org.springframework.web.context.WebApplicationContext;
import org.springframework.web.context.support.AnnotationConfigWebApplicationContext;
import org.springframework.web.servlet.support.AbstractDispatcherServletInitializer;

public class ServletContainersInitConfig extends AbstractDispatcherServletInitializer {
    //加载springmvc配置类
    protected WebApplicationContext createServletApplicationContext() {
        //初始化WebApplicationContext对象
        AnnotationConfigWebApplicationContext ctx = new AnnotationConfigWebApplicationContext();
        //加载指定配置类
        ctx.register(SpringMvcConfig.class);
        return ctx;
    }

    //设置由springmvc控制器处理的请求映射路径
    protected String[] getServletMappings() {
        return new String[]{"/"};
    }

    //加载spring配置类
    protected WebApplicationContext createRootApplicationContext() {
        return null;
    }
}

配置Tomcat

运行发现报错

问题补救

尝试将jdk版本降至1.8，将下面代码加入pom.xml文件中

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>2.3.2</version>
            <configuration>
                <source>1.8</source>
                <target>1.8</target>
            </configuration>
        </plugin>
    </plugins>
</build>

结果：没有任何作用，还是显示上述报错信息。

不用Tomcat7插件，用电脑下载的Tomcat，我这里电脑本地下载的Tomcat版本为8.5.75。

现在pom.xml文件内容如下

<?xml version="1.0" encoding="UTF-8"?>

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

          <target>1.8</target>
        </configuration>
      </plugin>
    </plugins>
  </build>

</project>

将上述的插件注释掉，然后使用电脑本地下载的Tomcat运行，结果发现报错

错误: 不支持发行版本 5

Language level is invalid or missing in pom.xml. Current project JDK is 16. Specify language level in springmvc01

查看，果然jdk版本莫名的变成了1.5

我们再使用插件将jdk升至1.8，将下述内容加至pom.xml文件中。

<build>
    <!--插件-->
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-compiler-plugin</artifactId>
        <version>2.3.2</version>
        <configuration>
          <source>1.8</source>
          <target>1.8</target>
        </configuration>
      </plugin>
    </plugins>
</build>

再运行，依然发现报错，报错信息如下

Caused by: java.lang.IllegalArgumentException: 找到多个名为spring_web的片段。这是不合法的相对排序。

我们导入的spring_web jar包重复了，所以需要删除一个

再点击运行，就可以了。总的来说也就是版本不匹配的问题，多调一下版本就可以了。
