spring boot自定义properties配置

在实际开发web时，有时需要自己添加一些配置。

一、application.properties配置

#致诚配置
zc.rsa_key_path=E:/xxx/xxx
zc.rc4_key=abcdefghijk
zc.userid=jinxiaoxin

二、自定配置类config

package com.xxxxx.config;

import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;

@Component
@ConfigurationProperties(prefix = "zc")
public class ZCConfig {
    private String rsa_key_path;
    private String rc4_key;
    private String userid;

    public String getRsa_key_path() {
        return rsa_key_path;
    }
    public void setRsa_key_path(String rsa_key_path) {
        this.rsa_key_path = rsa_key_path;
    }
    public String getRc4_key() {
        return rc4_key;
    }
    public void setRc4_key(String rc4_key) {
        this.rc4_key = rc4_key;
    }
    public String getUserid() {
        return userid;
    }
    public void setUserid(String userid) {
        this.userid = userid;
    }
}

三、Spring Boot入口类加上注解

//扫描config
@EnableConfigurationProperties
public class App extends SpringBootServletInitializer {

    public static void main(String[] args) {
        SpringApplication.run(App.class, args);
    }
    @Override
    protected SpringApplicationBuilder configure(
            SpringApplicationBuilder application) {
        return application.sources(App.class);
    }
}

四、如何使用

@Service
public class ZCServiceHandler {
    private static Logger LOG = Logger.getLogger(ZCServiceHandler.class);
    /**
     * 致诚配置内容
     */
    @Autowired
    //先注入
    ZCConfig zcConfig;

    public void useConfig(){
    String userId = zcConfig.getUserid();
    String rsaPubKeyFilePath = zcConfig.getRsa_key_path();// RSA 公钥绝对路径
    String rc4key = zcConfig.getRc4_key(); // RC4公钥
}
}
