Spring Boot 1.4.3搭建

Posted 2022-12-08 自在时刻

做项目时候，为了分出一个获取统一token的模块，采用spring boot进行项目构建。

pom.xml文件内容如下：

    </build>

</project>

因为使用了sqlserver数据库，所以添加了sqlserver驱动部分内容。

在resources文件夹下防止配置文件，application.properties:

spring.datasource.platform=mysql
spring.datasource.url=
spring.datasource.username=
spring.datasource.password=
spring.datasource.driverClassName=com.microsoft.sqlserver.jdbc.SQLServerDriver
# Advanced configuration...
spring.datasource.max-active=50
spring.datasource.max-idle=6
spring.datasource.min-idle=2
spring.datasource.initial-size=6

#create table
spring.jpa.hibernate.ddl-auto= validate



server.port=8888
server.session-timeout=30
server.tomcat.uri-encoding=UTF-8


spring.thymeleaf.prefix=classpath:templates/
spring.thymeleaf.suffix=.html
spring.thymeleaf.mode=HTML5
spring.thymeleaf.encoding=UTF-8
spring.thymeleaf.content-type=text/html
spring.thymeleaf.cache=false

---

定义的controller内容：

package mk.controller;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.bind.annotation.RestController;

/**
 * Created by yangyang on 17/1/26.
 */
@RestController
public class WeController 
    @RequestMapping(value = "/")
    public String index() 
        return "welcome";
    

---

定义application，作为spring boot入口。springboot同样要去指定的目录下扫描controller，service等各种组建来进行依赖注入，这部分的配置可以在入口通过componetScan指定扫描包名，不然无法找到相应的bean。运行Application的main方法，注意看到我们的 weController 是否成功启动。

package mk.boot;

import org.springframework.boot.CommandLineRunner;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.ApplicationContext;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;

import java.util.Arrays;

/**
 * Created by yangyang on 17/1/26.
 */

@SpringBootApplication
@ComponentScan(value = "mk.controller")
public class Application 
    public static void main(String[] args) 
        SpringApplication.run(Application.class, args);
    

    @Bean
    public CommandLineRunner commandLineRunner(final ApplicationContext ctx) 
        return new CommandLineRunner() 
            @Override
            public void run(String... strings) throws Exception 
                System.out.println("Let's inspect the beans provided by Spring Boot:");
                String[] beanNames = ctx.getBeanDefinitionNames();
                Arrays.sort(beanNames);
                for (String beanName : beanNames) 
                    System.out.println(beanName);
                
            
        ;

    

直接访问localhost:8888 即可看到我们的welcome页面。

以上通过spring boot，相当于整合了spring和spring mvc构建了一个基本的框架，但是数据访问层还没有进行整合，可以采用mybatis等。
