一，要修改启动的端口

只需要创建application.properties文件然后 加上一行

server.port=8083

既可

二，配置自定义常量

比如application.properties有 port=8081 

则

@Value("${port:8082}")
private String port;

即可获取8081这个值

三，单独的java对象映射

application.properties有如下配置：

connection.url=localhst
connection.username=gao
connection.remoteAddress=127.0.0.1
connection.password=123

@Component
@ConfigurationProperties(prefix = "connection")
public class AppConfig {private String url;private String username;private String remoteAddress;private String password;public String getUrl() {return url;}public void setUrl(String url) {this.url = url;}public String getUsername() {return username;}public void setUsername(String username) {this.username = username;}public String getRemoteAddress() {return remoteAddress;}public void setRemoteAddress(String remoteAddress) {this.remoteAddress = remoteAddress;}public String getPassword() {return password;}public void setPassword(String password) {this.password = password;}@Overridepublic String toString() {return "[url=" + url + ", username=" + username + ", remoteAddress=" + remoteAddress + ", password=" + password+ "]";}}

@Autowired
AppConfig appcf;

四，单独的配置文件，比如db.properties

db1.host=localhost
db1.port=80
db1.name=root
db1.psw=123

需要建立一个java类

@Component
@ConfigurationProperties(prefix="db1",locations="classpath:db.properties")
public class DBConfig {private String name;private String psw;private String host;private String port;public String getName() {return name;}public void setName(String name) {this.name = name;}public String getPsw() {return psw;}public void setPsw(String psw) {this.psw = psw;}public String getPort() {return port;}public void setPort(String port) {this.port = port;}public String getHost() {return host;}public void setHost(String host) {this.host = host;}@Overridepublic String toString() {return "DBConfig [name=" + name + ", psw=" + psw + ", host=" + host + ", port=" + port + "]";}}

然后用的时候

	@AutowiredDBConfig dbf;

在工程的配置文件不是非常复杂的情况下，推荐使用第三种方法
