pom:导入配置文件处理器，配置文件进行绑定就会有提示

yml:
user:
name: lisa
postcode: 610424199612112800
user.java方式一：使用@ConfigurationProperties注解实现批量对应属性值
package com.pecool.customer.entity;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;
@Component
@ConfigurationProperties(prefix="user")
public class User {
private String name;
private String postcode;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getPostcode() {
return postcode;
}
public void setPostcode(String postcode) {
this.postcode = postcode;
}
@Override
public String toString() {
return "User [name=" + name + ", postcode=" + postcode + "]";
}
}
user.java方式二：在属性上使用spring 的@Value注解也可以获取到yml或properties中的值
package com.pecool.customer.entity;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;
@Component
//@ConfigurationProperties(prefix="user")
public class User {
@Value("${user.name}")
private String name;
@Value("${user.postcode}")
private String postcode;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getPostcode() {
return postcode;
}
public void setPostcode(String postcode) {
this.postcode = postcode;
}
@Override
public String toString() {
return "User [name=" + name + ", postcode=" + postcode + "]";
}
}
Test.java
package com.pecool;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;
import com.pecool.customer.entity.User;
@SpringBootTest
@RunWith(SpringRunner.class)
public class TestA {
@Autowired
private User user;
@Test
public void xxx(){
System.out.println(user);
}
}
