四种方式可以获取到nacos里的配置信息

### 四种方式可以获取到nacos里的配置信息

前面两种没法动态获取，后面两种可以动态获取。

~~~java
@Component
public class TestValue1 {

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

@Value("${student.age}")
    private Integer age;

public String getName() {
        return name;
    }

public void setName(String name) {
        this.name = name;
    }

public Integer getAge() {
        return age;
    }

public void setAge(Integer age) {
        this.age = age;
    }
}
~~~

~~~java
@Component
@ConfigurationProperties(prefix = "student")
public class TestConfiguration1 {

private String name;
    private Integer age;

public String getName() {
        return name;
    }

public void setName(String name) {
        this.name = name;
    }

public Integer getAge() {
        return age;
    }

public void setAge(Integer age) {
        this.age = age;
    }
}

~~~

后面两种可以动态获取。

~~~java
@Component
@NacosPropertySource(dataId = "config-student.yaml", groupId = "monitor", autoRefreshed = true)
public class TestNacosValue1 {

@NacosValue(value = "${student.name}", autoRefreshed = true)
    private String name;

@NacosValue(value = "${student.age}", autoRefreshed = true)
    private Integer age;

public String getName() {
        return name;
    }

public void setName(String name) {
        this.name = name;
    }

public Integer getAge() {
        return age;
    }

public void setAge(Integer age) {
        this.age = age;
    }
}

~~~

~~~java
@Component
@NacosConfigurationProperties(dataId = "config-teacher.yaml", groupId = "monitor", prefix = "teacher", autoRefreshed = true)
public class TestNacosConfiguration1 {

private String name;
    private Integer age;

public String getName() {
        return name;
    }

public void setName(String name) {
        this.name = name;
    }

public Integer getAge() {
        return age;
    }

public void setAge(Integer age) {
        this.age = age;
    }
}
~~~

因为在application.yml中配置nacos的config的没有效果，所以使用注解的方式。

在启动类里添加：

~~~java
@EnableNacosConfig(globalProperties = @NacosProperties(serverAddr = "192.168.10.240:18848", namespace = "67cff043-6191-4def-b361-072aa169c944"))
