我正在使用Spring 4,并使用以下URL进行API调用
我有一个Java枚举类,其定义如下:
http://localhost.com:8080/int/fin/trs?bId=B-XYZ&sortBy=currentTs
而且,我有控制器方法,此调用正在接收参数:
public ResponseEntity<SetRESTData<FinancialTransactionDTO>> getTFIUse(
@RequestParam(value = "status", required = false) final String statusString,
@RequestParam(value = "transactionMappableEnumthod", required = false) final String transactionMappableEnumthodString,
@RequestParam(value = "sortBy", required = false) final String orderBy,
@RequestParam(value = "sortDirection", required = false) final String sortDirectionString) {
final FinancialTransactionPaginationData paginationData = StringUtils.isBlank(orderBy) ?
null : new FinancialTransactionPaginationData(FinancialTransactionSortableField.fromCode(orderBy), null, null, sortDirectionString);
}
FinancialTransactionSortableField类如下:
public enum FinancialTransactionSortableField implements MappableEnum<FinancialTransactionSortableField>, SF {
ID(DefaultSortableField.ID.getCode(), "T Id", DefaultSortableField.ID.getColumnNaMappableEnum()),
CREATED_TS(DefaultSortableField.CREATED_TS.getCode(),
DefaultSortableField.CREATED_TS.getDescription(),
DefaultSortableField.CREATED_TS.getColumnNaMappableEnum()),;
DefaultSortableField枚举类定义如下:
public enum DefaultSortableField implements MappableEnum<DefaultSortableField>, SF {
CREATED_TS("CreatedTs", "Created Timestamp", "CreatedTs"),;
private final String code;
private final String description;
private final String columnName;
private static final Map<String, DefaultSortableField> cmap =
MappableEnum.buildCodeMap(DefaultSortableField.class);
private DefaultSortableField(final String code, final String description, final String columnName) {
this.code = code;
this.description = description;
this.columnName = columnName;
}
@JsonValue
@Override
public String getCode() {
return code;
}
@Override
public String getDescription() {
return description;
}
@Override
public String getColumnName() {
return columnName;
}
@Override
public DefaultSortableField toEnum(final String code) {
return fromCode(code);
}
@JsonCreator
public static DefaultSortableField fromCode(final String code) {
return cmap.get(code);
}
}
我基本上是在进行api调用,例如http://localhost.com:8080/int/fin/trs?bId=B-XYZ&sortBy=CreatedTs
因此,当代码执行到达FinancialTransactionSortableField类的DefaultSortableField.CREATED_TS.getCode()方法时,将返回CreatedTs值(DefaultSortableField CREATED_TS枚举声明中的枚举的第一个参数。到目前为止,一切都很好,但是,当我通过时在上面的URL中,sortBy = createdTs(注意小写字母c)不起作用,我试图找出在哪里使用equalsIgnoreCase()方法,它将在FinancialTransactionSortableField类中的某个位置,还是在此行上的DefaultSortableField .CREATED_TS.getCode()
最佳答案
@JsonCreator
public static DefaultSortableField fromCode(final String code) {
for(String key : cmap.keySet()){
if(code.equalsIgnoreCase(key)){
return cmap.get(key);
}
}
return null;
}
