环境：
Spring-boot:2.1.2IDEA 2018.3MAVEN 3.6.0
1.热部署(hot swapping)
加入依赖：
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-devtools</artifactId>
<optional>true</optional>
</dependency>
一些设置：
2.对Date类型进行时间格式化，变成东八区时间：
@JsonFormat(timezone="GMT+8", pattern="yyyy-MM-dd")
private Date originRelease;
3.模拟http请求
建议用postman，因为curl的命令在windows下，在post请求，--data后面，本来的单引号要改成两个双引号，双引号要改成三个双引号，不然会报JSON Parse Error
curl -v localhost:8080/tvseries -H "Content-Type:application/json" -X POST --data ""{"""id""":1
000,"""originRelease""":"""2019-08-08"""}""
建议用postman软件代替在命令行中输入curl命令，可以避免上述问题：
4.以MySQL为例连接数据库
//首先添加依赖：
<dependency>
<groupId>org.mybatis.spring.boot</groupId>
<artifactId>mybatis-spring-boot-starter</artifactId>
<version>1.3.2</version>
</dependency>
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>8.0.13</version>
</dependency>
//然后再application.yml中添加数据库相关配置：
spring:
datasource:
driver-class-name: com.mysql.cj.jdbc.Driver
url: jdbc:mysql://127.0.0.1:3306/mydb?useUnicode=true&characterEncoding=UTF-8
&rewriteBatchedStatements=true&chara
username: root
password: 1234
@Repository
public interface TvSeriesDao
{
@Select("select * from tvseries")
List<TvSeries> getAll();
}
@Service
@Transactional
public class TvSeriesService
{
@Autowired private TvSeriesDao tvSeriesDao;
public List<TvSeries> getAllTvSeries() {
return tvSeriesDao.getAll();
}
}
//@MapperScan扫描dao所在类
@SpringBootApplication
@MapperScan("com.abc.bootdemo.dao")
public class Demo4Application
{
public static void main(String[] args)
{
SpringApplication.run(Demo4Application.class, args);
}
}
5.日志记录
application.yml:
logging:
file: target/app.log
level:
ROOT: warn
com.abc: trace
在方法中使用log：
@RestController
@RequestMapping("/tvseries")
public class TvSeriesController
{
private static final Log log = LogFactory.getLog(TvSeriesController.class);
@Autowired
TvSeriesService tvSeriesService;
@GetMapping
public List<TvSeries> getAll() {
if(log.isTraceEnabled()) {
log.trace("getAll():被调用了");
}
return tvSeriesService.getAllTvSeries();
}
}
console会输出：
2019-02-06 00:03:16.067 TRACE 668868 --- [nio-8080-exec-6] c.a.b.controller.TvSeriesController : getAll():被调用了
