spring boot使用application.properties默认了很多配置。但需要自己添加一些配置的时候，我们应该怎么做呢。
若继续在application.properties中添加
如：
1. wisely2.name=wyf2
2. wisely2.gender=male2
定义配置类：
1. @ConfigurationProperties(prefix = "wisely2")
2. public class Wisely2Settings {
3. private String name;
4. private String gender;
5. public String getName() {
6. return name;
7. }
8. public void setName(String name) {
9. this.name = name;
10. }
11. public String getGender() {
12. return gender;
13. }
14. public void setGender(String gender) {
15. this.gender = gender;
16. }
17.
18. }
若新用新的配置文件
如我新建一个wisely.properties
1. wisely.name=wangyunfei
2. wisely.gender=male
需定义如下配置类
1. @ConfigurationProperties(prefix = "wisely",locations = "classpath:config/wisely.properties")
2. public class WiselySettings {
3. private String name;
4. private String gender;
5. public String getName() {
6. return name;
7. }
8. public void setName(String name) {
9. this.name = name;
10. }
11. public String getGender() {
12. return gender;
13. }
14. public void setGender(String gender) {
15. this.gender = gender;
16. }
17.
18. }
最后注意在spring Boot入口类加上@EnableConfigurationProperties
1. @SpringBootApplication
2. @EnableConfigurationProperties({WiselySettings.class,Wisely2Settings.class})
3. public class DemoApplication {
4.
5. public static void main(String[] args) {
6. SpringApplication.run(DemoApplication.class, args);
7. }
8. }
使用定义的properties
1. @Controller
2. public class TestController {
3. @Autowired
4. WiselySettings wiselySettings;
5. @Autowired
6. Wisely2Settings wisely2Settings;
7.
8. @RequestMapping("/test")
9. public @ResponseBody String test(){
10. System.out.println(wiselySettings.getGender()+"---"+wiselySettings.getName());
11. System.out.println(wisely2Settings.getGender()+"==="+wisely2Settings.getGender());
12. return "ok";
13. }
14. }
