Spring boot uses the custom properties "Learn Spring boot from scratch"

Spring boot uses application.properties to default a number of configurations. But what should we do when we need to add some configuration for ourselves?

If you continue to add in application.properties

Such as:

1. Wisely2.name=wyf2

2. Wisely2.gender=male2

To define a configuration class:

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.}

One. public String Getgender () {

return gender;

13.}

Public void Setgender (String gender) {

. This . gender = gender;

16.}

17.

18.}

If new configuration file is used

As I create a new wisely.properties

1. Wisely.name=wangyunfei

2. Wisely.gender=male

You need to define the following configuration class

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.}

One. public String Getgender () {

return gender;

13.}

Public void Setgender (String gender) {

. This . gender = gender;

16.}

17.

18.}

Finally note the Spring boot entry class plus @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.}

Using the defined 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 () {

System.out.println (Wiselysettings.getgender () + "---" +wiselysettings.getname ());

One. System.out.println (Wisely2settings.getgender () + "= = =" +wisely2settings.getgender ());

return "OK";
