1、配置一个springboot的主类方法

com.companyname.projectname.SpringbootauthApplication.java

package com.companyname.projectname;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.freemarker.FreeMarkerAutoConfiguration;
import org.springframework.transaction.annotation.EnableTransactionManagement;
@SpringBootApplication(exclude = { FreeMarkerAutoConfiguration.class })
@EnableTransactionManagement
@MapperScan(basePackages={
"com.companyname.projectname.modular.base.mapper",
})
public class SpringbootauthApplication {

    public static void main(String[] args) {
        SpringApplication.run(SpringbootauthApplication.class, args);
    }
}

2、配置一个打包war使用的主类
com.companyname.projectname.SpringbootauthServletInitializer.java

package com.companyname.projectname;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.freemarker.FreeMarkerAutoConfiguration;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;
import org.springframework.transaction.annotation.EnableTransactionManagement;

/**
 * Guns Web程序启动类
 */
@SpringBootApplication(exclude = { FreeMarkerAutoConfiguration.class })
@MapperScan(basePackages={
"com.companyname.projectname.modular.base.mapper",
})
@EnableTransactionManagement
public class SpringbootauthServletInitializer extends SpringBootServletInitializer {
    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        return builder.sources(SpringbootauthServletInitializer.class);
    }
    public static void main(String[] args) {
        SpringApplication.run(SpringbootauthServletInitializer.class, args);
    }
}

3、配置maven pom.xml 打包方式

<build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <configuration>
                    <mainClass>com.companyname.projectname.SpringbootauthApplication</mainClass>
                </configuration>
				  <executions>
                    <execution>
                        <goals>
                            <goal>repackage</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-war-plugin</artifactId>
                <version>3.2.3</version>
                <configuration>
                    <failOnMissingWebXml>false</failOnMissingWebXml>
                    <resourceEncoding>${project.build.sourceEncoding}</resourceEncoding>
                </configuration>
            </plugin>
        </plugins>
	    <resources>
	 		 <resource>
	             <directory>src/main/resources</directory>
	         </resource>
	         <resource>
	             <directory>src/main/java</directory>
	             <includes>
	                 <include>**/*.xml</include>
	             </includes>
	         </resource>
	       </resources>
    </build>
