Method Detail

convert

@Nullable
public static <T> T convert(@Nullable
                                      Object source,
                                      Class<T> targetType)

Convenience operation for converting a source object to the specified targetType. TypeDescriptor.forObject(Object).

Type Parameters:

T - 泛型标记

Parameters:

source - the source object

targetType - the target type

Returns:

the converted value

Throws:

IllegalArgumentException - if targetType is null, or sourceType is null but source is not null

convert

@Nullable
public static <T> T convert(@Nullable
                                      Object source,
                                      org.springframework.core.convert.TypeDescriptor sourceType,
                                      org.springframework.core.convert.TypeDescriptor targetType)

Convenience operation for converting a source object to the specified targetType, where the target type is a descriptor that provides additional conversion context. TypeDescriptor.forObject(Object).

Type Parameters:

T - 泛型标记

Parameters:

source - the source object

sourceType - the source type

targetType - the target type

Returns:

the converted value

Throws:

IllegalArgumentException - if targetType is null, or sourceType is null but source is not null

convert

@Nullable
public static <T> T convert(@Nullable
                                      Object source,
                                      org.springframework.core.convert.TypeDescriptor targetType)

Convenience operation for converting a source object to the specified targetType, where the target type is a descriptor that provides additional conversion context. Simply delegates to convert(Object, TypeDescriptor, TypeDescriptor) and encapsulates the construction of the source type descriptor using TypeDescriptor.forObject(Object).

Type Parameters:

T - 泛型标记

Parameters:

source - the source object

targetType - the target type

Returns:

the converted value

Throws:

IllegalArgumentException - if targetType is null, or sourceType is null but source is not null
