現(xiàn)象描述：

spring boot 在eclipse里啟動正常，但打包后啟動不起來。

錯(cuò)誤日志如下：

問題解決路徑

1. 最初懷疑是打包時(shí)缺少依賴包造成的，修改打包的方式

<build><finalName>xxxxx</finalName><plugins><plugin><groupId>org.apache.maven.plugins</groupId><artifactId>maven-compiler-plugin</artifactId><configuration><source>1.8</source><target>1.8</target><encoding>UTF-8</encoding></configuration></plugin><plugin><groupId>org.springframework.boot</groupId><artifactId>spring-boot-maven-plugin</artifactId><configuration><fork>true</fork><mainClass>com.xx</mainClass><layout>ZIP</layout> </configuration><executions><execution><goals><goal>repackage</goal></goals></execution></executions></plugin></plugins></build>

依賴包沒有問題，還是報(bào)同樣的錯(cuò)誤。

2. 排除依賴包的問題后，懷疑是jar包沖突的問題，網(wǎng)上有類似的

https://stackoverflow.com/questions/32758000/java-lang-illegalstateexception-error-processing-condition-on-org-springframewo

使用dependence查了? 沒有不同版本的依賴，排除

3.懷疑是*config.java的配置問題，一個(gè)個(gè)移除進(jìn)行測試，也排除掉了

4.根據(jù)日志懷疑是Controller里排除的異常頁面有問題，排查后沒有發(fā)現(xiàn)

5.懷疑是application_*.properties的配置問題

? ?一項(xiàng)項(xiàng)排查，發(fā)現(xiàn)跟這個(gè)有關(guān)

spring.thymeleaf.prefix=static:/web/

去除這個(gè)選項(xiàng)后，重新打包后可以啟動成功。
