Question

通常，我使用一个类从yml加载所有配置，并通过自动装配配置使它们在我的应用程序中可用。在我尝试通过添加@Validated批注来验证配置之前，此方法效果很好。

如果验证失败，则应用程序无法启动，并且我收到一条消息，其中包含设置错误的属性。如果验证成功，即使通过调试也可以看到，我的自动装配配置为空，即使从yml文件读取并设置了正确的值。

//full configuration class
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;
import org.springframework.validation.annotation.Validated;

import javax.validation.Valid;
import javax.validation.constraints.NotBlank;

@Component
@ConfigurationProperties(prefix = "config")
@Validated
public class ConfigurationStore {

    @Valid
    public MyConfiguration myConfiguration = new MyConfiguration();

    public ConfigurationStore setMyConfiguration(MyConfiguration myConfiguration) {
        this.myConfiguration = myConfiguration;
        return this;
    }

    public static class MyConfiguration {

        @NotBlank
        public String configuredString;

        public void setConfiguredString(String configuredString) {
            this.configuredString = configuredString;
        }
    }

}

//class where autowired configuration is always null
import {package}.ConfigurationStore;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Import;

@Configuration
@Import(ConfigurationStore.class)
public class MyConfig {

    private ConfigurationStore configurationStore;

    @Autowired
    public MyConfig(ConfigurationStore configurationStore) {
        this.configurationStore = configurationStore;
    }

    @Bean
    public String returnIt() {
        return configurationStore.myConfiguration.configuredString;
    }
}

删除@Validated会删除验证功能。保留它会导致自动装配配置为空。我期望的是配置和验证可以同时进行。

Spring：使用@Validated注释时，自动装配配置为null
