我无法在弹簧休息控制器中读取下面的自定义对象列表。但是，能够通过将bean自动装入restcontoller中的java bean来读取/获取数据。 任何人都可以帮助我使用annonation @value从rest控制器读取数据列表吗？无法解析占位符字符串值中的自定义对象列表
无法解析占位符字符串值“$ {royalty.testRates}”中的自定义对象列表（royalty.testRates）。对于YAML文件
代码片段：
testRates:
- channelType: "WEB"
value: "0.03"
- channelType: "ANDROID_TAB"
value: "0.04"
- channelType: "ANDROID_PHONE"
value: "0.04"
代码片段的Java文件： 的Java Bean：
@EnableAsync
@Configuration
@EnableConfigurationProperties
@ConfigurationProperties(ignoreInvalidFields = false, prefix = "royalty")
@Component
public class RoyaltyMigration {
private List<TestRate> testRates = new ArrayList<TestRate>();
public static class TestRate {
private String channelType;
private String value;
public List<TestRate> getTestRates() {
return testRates;
}
public void setTestRates(List<TestRate> testRates) {
this.testRates = testRates;
}
public String getChannelType() {
return channelType;
}
public void setChannelType(String channelType) {
this.channelType = channelType;
}
public String getValue() {
return value;
}
public void setValue(String value) {
this.value = value;
}
}
弹簧安置控制器：
//@Autowired//Commented
//RoyaltyMigration royaltyMigration; //Commented
@Value("${royalty.testRates}")
private List<RoyaltyMigration.TestRate> testRates;//= new ArrayList<RoyaltyMigration.TestRate>();;
public void setTestRates(List<RoyaltyMigration.TestRate> testRates) {
this.testRates = testRates;
}
@RequestMapping(value = "/testrates", method = {RequestMethod.GET, RequestMethod.POST},
produces = "application/json")
public ResponseEntity<RoyaltyMigration> testRates() {
final RoyaltyMigration royaltyMigration = new RoyaltyMigration();
royaltyMigration.setTestRates(this.testRates);
return new ResponseEntity<>(royaltyMigration, HttpStatus.OK);
}
