    		</plugins>

注意：

在继承parent是：

<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>1.5.1.RELEASE</version>
    </parent>

maven-resources-plugin 2.6.3版本无法下载，所以：

在pom的build里面：进行了一下覆盖成2.7：

<plugin>
					<groupId>org.apache.maven.plugins</groupId>
					<artifactId>maven-resources-plugin</artifactId>
					<version>2.7</version>
					<configuration>
						<delimiters>
							<delimiter>${resource.delimiter}</delimiter>
						</delimiters>
						<useDefaultDelimiters>false</useDefaultDelimiters>
					</configuration>
				</plugin>

其他：

在启动文件中，注意；两个注解：

@SpringBootApplication

@MapperScan("haust.vk.dao")

解释：

1.SpringBootApplication

这是一个多注解封装的组合注解，使用exclude可以排除其中的注解。
