Question

我正在构建一个Rest WS并验证我正在使用JSR-303 BeanValidation的请求元素，但是有一个字段类型Enum。

EmploymentType.java

public enum EmploymentType {
    EMPTY, FULL, PARTTIME, CONTRACT, CASUAL;

    public static EmploymentType getDefaultEnum() {
        return EMPTY;
    }
}

和我用来实现这个的类：

Employment.java

public class Employment implements Serializable{

    private static final long serialVersionUID = 1L;

    @NotNull(message="employmentType does not accept null values")
    private EmploymentType employmentType;

    @Valid
    @NotNull(message="orgData does not accept null values")
    private OrgData orgData;

    public Employment() {
        employmentType = EmploymentType.getDefaultEnum();
        orgData = new OrgData();
    }

    public EmploymentType getEmploymentType() {
        return employmentType;
    }

    public void setEmploymentType(EmploymentType employmentType) {
        this.employmentType = employmentType;
    }

    public OrgData getOrgData() {
        return orgData;
    }

    public void setOrgData(OrgData orgData) {
        this.orgData = orgData;
    }
}

我开发的实现只能阻止枚举为空对象，有没有办法验证枚举的值是否只在声明值的范围内？（空，全，合同，合同，休闲）

我相信你必须验证valueOf或枚举的名称以下是将验证发生的摘录

public class Employment implements Serializable {

@NotNull(message = "employmentType does not accept null values")
@Valid
private EmploymentType employmentType;

public EmploymentType getEmploymentType() {
    getEmploymentTypeOfEnum();
    return employmentType;
} 

@Pattern(regexp = "EMPTY|FULL")
private String getEmploymentTypeOfEnum(){ // you don't need it to be public
     return employmentType.name();
}
}

如何为Enums实现JSR-303
