概述
上篇记录了IDEA上创建Maven SpringBoot+mybatisplus+thymeleaf 项目，但是如何将SpringBoot发布到Tomcat，直接采用Maven 命令Clear-Package指令之后，生成的War并不能访问，任然显示404错误。所以这个时候，需要修改代码内容部分；
代码调整项
1、修改pom.xml文件；
(1)、finalName要和Application.properties中的server.context-path值保持一致；
<build>
<finalName>htcv</finalName>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<source>${jdk.version}</source>
<target>${jdk.version}</target>
</configuration>
</plugin>
</plugins>
(2)、pom加上javax.servlet.servlet-api依赖项；
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>servlet-api</artifactId>
<version>3.0-alpha-</version>
</dependency>
(3)、发布的时候排除内嵌tomcat服务器，避免冲突；
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
<exclusions>
<exclusion>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
</exclusion>
</exclusions>
</dependency>
完整的pom.xml配置如下，记得将<packaging>jar</packaging>修改成<packaging>war</packaging>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

<target>${jdk.version}</target>
</configuration>
</plugin>
</plugins>
</build> </project>
2、修改java文件内；
让程序入口Main方法类继承SpringBootServletInitializer，重写configure方法；
import com.justin.model.Einvoice;
import com.justin.serviceapi.EinvoiceService;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.Banner;
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.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController; @SpringBootApplication
@RestController
@MapperScan("com.justin.dao")
public class Application extends SpringBootServletInitializer
{
@Autowired
private EinvoiceService einvoiceservice; @RequestMapping("/")
public String Greeting()
{
return "Justin Say Hello WOrld!";
} @RequestMapping("/Add")
public String AddEinvoice()
{
Einvoice Einv=new Einvoice();
Einv.setInvoicecode("");
Einv.setInvoicenum("");
einvoiceservice.insertOne(Einv);
return "INser SUCC";
} @RequestMapping("/check/{invoicecode}")
public String ShowInfo(@PathVariable("invoicecode") String invoicecode)
{
return einvoiceservice.GetInvoiceNUmByCode(invoicecode);
}
@RequestMapping("/Update/{invoicecode}/{invoicenum}")
public String UpInfo(@PathVariable("invoicecode") String invoicecode,@PathVariable("invoicenum") String invoicenum)
{
einvoiceservice.ChangeCode(invoicenum,invoicecode);
return "SUCC";
} public static void main(String[] args)
{
SpringApplication.run(Application.class,args); } @Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
return configureApplication(builder);
} private static SpringApplicationBuilder configureApplication(SpringApplicationBuilder builder) {
return builder.sources(Application.class).bannerMode(Banner.Mode.OFF);
}
}
重新打包发布即可，输入网址 http://localhost:8080/htcv//HE/CIndex 即可访问自定义的页面内容项；
