spirngboot依赖与注解(一)

pom文件web依赖

<dependency>
	<groupId>org.springframework.boot</groupId>
	<artifactId>spring-boot-starter-web</artifactId>
</dependency>

pom文件webflux依赖

<dependency>
	<groupId>org.springframework.boot</groupId>
	<artifactId>spring-boot-starter-webflux</artifactId>
</dependency>

pom文件热部署依赖

dependency>
	<groupId>org.springframework.boot</groupId>
	<artifactId>spring-boot-starter-devtools</artifactId>
	<scope>runtime</scope>
</dependency>

@Value注解

@Value注解取出properties配置文件中的自定义属性
properties自定义属性

book.name = Springboot

@Value注解使用

@Value("${book.name}")
private String bookName;

properties配置文件使用随机数

#随机字符串
book.value = ${random.value}

还有random.int, random.uuid,random.int(1000)等

@ConfigurationProperties(prefix = “”)与@EnableConfigurationProperties注解

@ConfigurationProperties(prefix = “”)前缀取出properties配置文件中的值
properties

book.value = ${random.value}
book.intValue = ${random.int}
book.longValue = ${random.long}
book.uuid = ${random.uuid}

使用javaBean模式给属性赋值

@ConfigurationProperties(prefix = "book")
public class BookConfigBean{
    private String value;
    private String intValue;
    private String longValue;
    private String uuid;
};

在启动类加入@EnableConfigurationProperties(BookConfigBean.class),表明启动这个配置类
在Controller使用@Autowired注入配置类

public class TestController{

    @Autowried
    private BookConfigBean bookConfigBean;

    @GetMapping("test2")
    public BookConfigBean test2(){
        return bookConfigBean;
    }

}
