讀取配置SpringBoot配置文件三種方式
一、利用Bean注解中的Value(${})注解
|
1
2
3
4
5
6
|
@Data@Componentpublic class ApplicationProperty { @Value("${application.name}") private String name;} |
該方式可以自動(dòng)讀取當(dāng)前配置文件appliation.yml 或者application.properties中的配置值
區(qū)別在于讀取yml文件時(shí)候支持中文編碼，peoperties需要轉(zhuǎn)碼
二、利用@ConfigurationProperties(prefix = "developer")注解

5

8
9
|
@Data@ConfigurationProperties(prefix = "developer")@Componentpublic class DeveloperProperty { private String name; private String website; private String qq; private String phoneNumber;} |
該方式直接將當(dāng)前加載yml配置文件前綴為developer的屬性
讀取developer.name...
pom文件中引入依賴

//使用方法private final ApplicationProperty applicationProperty;private final DeveloperProperty developerProperty;@Autowired public PropertyController(ApplicationProperty applicationProperty, DeveloperProperty developerProperty) { this.applicationProperty = applicationProperty; this.developerProperty = developerProperty; }@GetMapping("/property") public Dict index() { System.out.println("name:"+applicationProperty.getName()); System.out.println("version:"+applicationProperty.getVersion()); System.out.println("DevName:"+applicationProperty.getDeveloperName()); } |
四、用Hutool的方式讀取配置文件(不支持yml格式)
1.用Props的方式讀取
|
1
|
static Props props1 = new Props("application.properties",CharsetUtil.CHARSET_UTF_8); |
2.用Setting的方法讀取
|
1
|
static Setting setting = new Setting("application-dev.yml", CharsetUtil.CHARSET_UTF_8,true); |
3.將配置文件讀取

public class Constant { static Props props1 = new Props("application.properties",CharsetUtil.CHARSET_UTF_8); static Setting setting = new Setting("application-dev.properties", CharsetUtil.CHARSET_UTF_8,true); public static final String Name ; public static final String SettingName ; static { Name = props.getStr("application.name"); SettingName = setting.getByGroup("name","application"); }} |
4.使用方式
|
1
|
System.out.println(Constant.DevName+"------"+Constant.DevWebsite); |
直接用常量類調(diào)用該類屬性即可使用
