springboot项目打成war包部署到tomcat遇到的一些问题

开发环境使用jdk1.8.0_60，把springboot 项目打成war包后，

部署到apache-tomcat-7.0.68时报错如下，换成apache-tomcat-8.0.9解决

另外springboot项目打成war包部署到tomcat时需要改变启动方式，否则运行tomcat时war包只会解压，但是加载不了

import org.springframework.boot.SpringApplication;

import org.springframework.boot.autoconfigure.EnableAutoConfiguration;

import org.springframework.boot.autoconfigure.SpringBootApplication;

import org.springframework.boot.builder.SpringApplicationBuilder;

import org.springframework.boot.context.web.SpringBootServletInitializer;

@SpringBootApplication //- springboot项目,并配置扫描路径

@EnableAutoConfiguration //- springboot自动配置，这个注解可以根据你依赖的包自动生成相关配置

public class StartApp extends SpringBootServletInitializer {

public static void main(String[] args) {

SpringApplication.run(StartApp.class, args);

}

/**

* 需要把web项目打成war包部署到外部tomcat运行时需要改变启动方式

*/

@Override

protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {

return builder.sources(StartApp.class);

}

部署到外部tomcat时，注意pom.xml配置，否则会报错

org.springframework.boot

spring-boot-starter-tomcat

1.3.5.RELEASE

provided

**报错信息：**

springboot项目使用jsp页面时会添加以下依赖，但是在外部tomcat运行时会报错

因为tomcat /lib下自带的jar包（jasper.jar，jsp-api.jar等）会跟war包项目路径/lib下的解析jsp的jar包冲突

删除项目路径/lib下的相关jar包即可，如下图

org.apache.tomcat.embed

tomcat-embed-jasper

8.0.33

**报错信息：**

[ERROR][2017-06-22 00:48:28,303][org.springframework.boot.context.web.ErrorPageFilter]Forwarding to error page from request [/excel] due to exception [java.lang.LinkageError: loader constraint violation: when resolving method "org.apache.jasper.runtime.InstanceManagerFactory.getbetnbZzVcInstanceManager(Ljavax/servlet/ServletConfig;)Lorg/apache/tomcat/InstanceManager;" the class loader (instance of org/apache/jasper/servlet/JasperLoader) of the current class, org/apache/jsp/jsp/excel_jsp, and the class loader (instance of java/net/URLClassLoader) for the method's defining class, org/apache/jasper/runtime/InstanceManagerFactory, have different Class objects for the type org/apache/tomcat/InstanceManager used in the signature]

默认配置下就可以通过http://localhost:8080/war包名/@RequestMapping.value访问了， 另外部署到tomcat后静态资源（resources下的js文件）访问不到的问题还没解决。。。
