Spring Roo 2.0.RC1 - 構建wariv Archiv並在外部Tomcat中部署

Question

我不想在外部Tomcat中使用Spring Roo創建項目中的war立方體。

我使用與MySQL

像其它的啓動應用程序，我有改變的pom.xml和起動器類診所例子。

在pom.xml中

變化：<packaging>war</packaging>建立一個戰爭檔案館

變化Java版本7

補充說：

<dependency> 
    <groupId>org.springframework.boot</groupId> 
    <artifactId>spring-boot-starter-tomcat</artifactId> 
    <scope>provided</scope> 
</dependency> 

嵌入式tomca牛逼庫將投入戰爭檔案館WEB-INF/lib目錄提供的在沒有WEB-INF/lib目錄

入門級的變化

package org.springframework.roo.petclinic; 

import org.springframework.boot.SpringApplication; 
import org.springframework.boot.autoconfigure.SpringBootApplication; 
import org.springframework.boot.builder.SpringApplicationBuilder; 
import org.springframework.boot.web.support.SpringBootServletInitializer; 

/** 
* = PetclinicApplication 
* 
* TODO Auto-generated class documentation 
* 
*/ 
@SpringBootApplication 
public class PetclinicApplication extends SpringBootServletInitializer { 

    @Override 
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) { 
     return application.sources(PetclinicApplication.class); 
    } 

    /** 
    * TODO Auto-generated method documentation 
    * 
    * @param args 
    */ 
    public static void main(String[] args) { 
     SpringApplication.run(PetclinicApplication.class, args); 
    } 
} 

但是當我把外部的Tomcat 7（XAMPP）戰爭檔案館我get stacktrace

在pom.xml中提供了mysql驅動程序並將其刪除，但應用程序不會在tomcat中啓動。 （相同的堆棧跟蹤）

我已經測試了一些其他的spring啓動例子，並且這些改變使應用程序在外部tomcat中啓動。

什麼樣的變化爲外部雄貓打造工作戰爭？

Answer 1

有一天我遇到了PostgresSQL JDBC驅動程序的問題。

要解決這個問題，您應該在tomcat安裝的/lib文件夾中包含MySQL JDBC driver。

希望它有幫助，
