Spring Boot Custom Configuration

Customizing the configuration item in spring boot is just one of the ways to implement it

Application.properties

Alipay.url = Https://openapi.alipaydev.com/gateway.doalipay.format = Jsonalipay.charset = UTF-8alipay.sign_ Type = RSA2 

The first way:

Customizing an entity class for a configuration property

1@ConfigurationProperties (prefix = "Alipay")2 @Component3  Public classalipayconfiguration {4 5     PrivateString URL;//Request Address6     PrivateString format;//Request Data Format7     PrivateString CharSet;//request data encoding format8     PrivateString Sign_type;//Signature Method9 Ten      PublicString GetUrl () { One         returnURL; A     } -  -      Public voidseturl (String url) { the          This. url =URL; -     } -  -      PublicString GetFormat () { +         returnformat; -     } +  A      Public voidsetformat (String format) { at          This. Format =format; -     } -  -      PublicString Getcharset () { -         returnCharSet; -     } in  -      Public voidSetcharset (String charset) { to          This. CharSet =CharSet; +     } -  the      PublicString Getsign_type () { *         returnSign_type; $     }Panax Notoginseng  -      Public voidSetsign_type (String sign_type) { the          This. Sign_type =Sign_type; +     } A  the}

Use

@Service  Public class Implements alipayservice{        @Autowired    private  alipayconfiguration alipayconfig;           Public void GetUrl () {            System.out.println (Alipayconfig.geturl ());        }        
}
