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

    
      
      
 src/main/resources
 false
      
      
      
 src/main/webapp
 meta-INF/resources
 false
      
    

    
      
 org.springframework.boot
 spring-boot-maven-plugin
 
      
       
 org.apache.maven.plugins 
 maven-surefire-plugin 
  
   true 
  
      
    
  

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”

    
      
      
 src/main/resources
 false
      
      
      
 src/main/webapp
 meta-INF/resources
 false
      
    

    
      
 org.springframework.boot
 spring-boot-maven-plugin
 1.4.2.RELEASE
      
       
 org.apache.maven.plugins 
 maven-surefire-plugin 
  
   true 
  
      
    
  

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

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.

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