问题解决路径

1. 最初怀疑是打包时缺少依赖包造成的，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>

依赖包没有问题，还是报同样的错误。

2. 排除依赖包的问题后，怀疑是jar包冲突的问题，网上有类似的

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

使用dependence查了  没有不同版本的依赖，排除

3.怀疑是*config.java的配置问题，一个个移除进行测试，也排除掉了

4.根据日志怀疑是Controller里排除的异常页面有问题，排查后没有发现

5.怀疑是application_*.properties的配置问题

一项项排查，发现跟这个有关

spring.thymeleaf.prefix=static:/web/

去除这个选项后，重新打包后可以启动成功。
