jhipster - 在哪里以及如何定义应用程序属性？ - JHIpster

Question

在 Spring Boot 中，可以在 application.properties 文件中定义应用程序属性。例如，Rest 的前缀可以定义为

spring.data.rest.basePath=api

对于基于 Spring Boot 的 JHipster，我猜可以在 application.yml 文件中定义一个应用程序属性。但是以下方法都不适合我:404 错误。

spring.data.rest.basePath: api

spring:
    data:
        rest:
            basePath: api

另一种可能性是配置本身不起作用。

我有同样的问题，终于想通了!
引用自 Jhipster 网站:

Your generated application can also have its own Spring Boot properties. This is highly recommended, as it allows type-safe configuration of the application, as well as auto-completion and documentation within an IDE.

JHipster has generated a ApplicationProperties class in the config package, which is already preconfigured, and it is already documented at the bottom the application.yml, application-dev.yml and application-prod.yml files. All you need to do is code your own specific properties.

就我而言，我已经在 applicaiton-prod.yml 中设置了属性

application:
    redis:
        host: vnode1
        pool:
            max-active: 8
            max-idle: 8
            max-wait: -1
            min-idle: 0
        port: 6379

在 ApplicationProperties 类中:

@ConfigurationProperties(prefix = "application", ignoreUnknownFields = false)
public class ApplicationProperties {

    public final Redis redis = new Redis();

    public Redis getRedis() {
        return redis;
    }

    public static class Redis {

        private String host = "127.0.0.1";

        private int port = 0;

        public String getHost() {
            return host;
        }

        public void setHost(String host) {
            this.host = host;
        }

        public int getPort() {
            return port;
        }

        public void setPort(int port) {
            this.port = port;
        }

        private Pool pool = new Pool();

        public void setPool(Pool pool) {
            this.pool = pool;
        }

        public Pool getPool() {
            return this.pool;
        }

        public static class Pool {
            private int maxActive = 8;
            private int maxWait = -1;

            public int getMaxIdle() {
                return maxIdle;
            }

            public void setMaxIdle(int maxIdle) {
                this.maxIdle = maxIdle;
            }

            private int maxIdle = 8;
            private int minIdle = 0;


            public void setMaxActive(int maxActive) {
                this.maxActive = maxActive;
            }

            public int getMaxActive() {
                return maxActive;
            }

            public int getMinIdle() {
                return minIdle;
            }

            public void setMinIdle(int minIdle) {
                this.minIdle = minIdle;
            }

            public int getMaxWait() {
                return maxWait;
            }

            public void setMaxWait(int maxWait) {
                this.maxWait = maxWait;
            }
        }

    }
}

然后我将其用作:

private final ApplicationProperties.Redis redis;
public RedisConfiguration(ApplicationProperties applicationProperties){
    redis = applicationProperties.getRedis();
}

例如使用 max-wait和 host :

this.redis.getPool().getMaxWait();
this.redis.getHost();

希望能帮助到你。
