Spring打包jar包时jsp页面无法访问问题解决

spring打包jar包时jsp页面无法访问

问题如下

当前pom.xml配置

<build>
    <resources>
      <!--引入配置文件-->
      <resource>
        <directory>src/main/resources</directory>
        <filtering>false</filtering>
      </resource>
      <!--引入静态文件-->
      <resource>
        <directory>src/main/webapp</directory>
        <targetPath>META-INF/resources</targetPath>
        <filtering>false</filtering>
      </resource>
    </resources>

    <plugins>
      <plugin>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-maven-plugin</artifactId>
        
      </plugin>
      <plugin> 
        <groupId>org.apache.maven.plugins</groupId> 
        <artifactId>maven-surefire-plugin</artifactId> 
        <configuration> 
          <skipTests>true</skipTests> 
        </configuration> 
      </plugin>
    </plugins>
  </build>

解决办法：

1.高版本的插件不支持jsp，给spring-boot-maven-plugin指定版本号“1.4.2.RELEASE”

<build>
    <resources>
      <!--引入配置文件-->
      <resource>
        <directory>src/main/resources</directory>
        <filtering>false</filtering>
      </resource>
      <!--引入静态文件-->
      <resource>
        <directory>src/main/webapp</directory>
        <targetPath>META-INF/resources</targetPath>
        <filtering>false</filtering>
      </resource>
    </resources>

    <plugins>
      <plugin>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-maven-plugin</artifactId>
        <version>1.4.2.RELEASE</version>
      </plugin>
      <plugin> 
        <groupId>org.apache.maven.plugins</groupId> 
        <artifactId>maven-surefire-plugin</artifactId> 
        <configuration> 
          <skipTests>true</skipTests> 
        </configuration> 
      </plugin>
    </plugins>
  </build>

2.根据spring官网说明，可打包war包，仍然可使用jar -jar xxx.war执行。

https://docs.spring.io/spring-boot/docs/current/reference/htmlsingle/#boot-features-jsp-limitations

JSP Limitations
When running a Spring Boot application that uses an embedded servlet container (and is packaged as an executable archive), there are some limitations in the JSP support.

With Jetty and Tomcat, it should work if you use war packaging. An executable war will work when launched with java -jar, and will also be deployable to any standard container. JSPs are not supported when using an executable jar.

Undertow does not support JSPs.

Creating a custom error.jsp page does not override the default view for error handling. Custom error pages should be used instead.

<packaging>war</packaging>

https://docs.spring.io/spring-boot/docs/current/reference/htmlsingle/#boot-documentation

spring官方不推荐使用jsp，推荐使用thymeleaf、freemaker、velocity等其他模块引擎。
