把配置文件写到application.yml或application.properties中，有时我们不愿意把配置都写到application配置文件中，这时需要我们自定义配置文件，比如test.properties:
com.forezp.name=forezpcom.forezp.age=12
怎么将这个配置文件信息赋予给一个javabean呢？
@Configuration@PropertySource(value = "classpath:test.properties")@ConfigurationProperties(prefix = "com.forezp")public class User {
private String name;
private int age;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}}在最新版本的springboot，需要加这三个注解。@Configuration @PropertySource(value = “classpath:test.properties”) @ConfigurationProperties(prefix = “com.forezp”);在1.4版本需要 PropertySource加上location。
@RestController@EnableConfigurationProperties({ConfigBean.class,User.class})public class LucyController {
@Autowired
ConfigBean configBean;
@RequestMapping(value = "/lucy")
public String miya(){
return configBean.getGreeting()+" >>>>"+configBean.getName()+" >>>>"+ configBean.getUuid()+" >>>>"+configBean.getMax();
}
@Autowired
User user;
@RequestMapping(value = "/user")
public String user(){
return user.getName()+user.getAge();
}}启动工程，打开localhost:8080/user;浏览器会显示：
