springboot-jsp tomcat部署

1.项目结构 使用apache-tomcat-8.0.48版本(7.0版本会报空指针)

2.pom文件

2.1 首先要修改 package 方式

<packaging>war</packaging>

2.2 对 spring-boot-starter-web  排除自带的tomcat包,使用Apache tomcat

	<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-web</artifactId>
			<!-- 其次spring boot的web项目中内嵌tomcat服务器，所以如果我们想要发布war包到tomcat项目，要讲spring 
				boot中内嵌的tomcat包依赖排除，不然产生冲突，打开下面代码中的注释即可。 -->
			<exclusions>
				<exclusion>
					<groupId>org.springframework.boot</groupId>
					<artifactId>spring-boot-starter-tomcat</artifactId>
				</exclusion>
			</exclusions>
		</dependency>

2.3 添加servlet 

<!--配置servlet -->
		<dependency>
			<groupId>javax.servlet</groupId>
			<artifactId>javax.servlet-api</artifactId>
		</dependency>

4.启动类 LockApplication.java

package lock;

import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.support.SpringBootServletInitializer;
import org.springframework.context.annotation.Bean;
import org.springframework.transaction.annotation.EnableTransactionManagement;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;

@SpringBootApplication
@MapperScan(basePackages = "lock.dao")
@EnableTransactionManagement
public class LockApplication extends SpringBootServletInitializer {

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

	@Override
	protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
		return builder.sources(LockApplication.class);
	}

}

4.1 LockApplication类继承 SpringBootServletInitializer类并重写protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) 方法

protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
		return builder.sources(LockApplication.class);
	}
