isTrue

public static void isTrue(boolean expression,
                          String name)

Assert a boolean expression, throwing an IllegalStateException if the expression evaluates to false.

AssetUtils.state(id == null, "name");

参数:

expression - a boolean expression

name - the exception message to use if the assertion fails like 'name is not true'

抛出:

ServiceException - if expression is false

isNull

public static void isNull(@Nullable
                          Object object,
                          String name)

Assert that an object is null.

AssetUtils.isNull(value, "name");

参数:

object - the object to check

name - the exception message to use if the assertion fails

抛出:

ServiceException - if the object is not null 'name must be null!'

notNull

public static void notNull(@Nullable
                           Object object,
                           String name)

Assert that an object is not null.

AssetUtils.notNull(clazz, "name");

参数:

object - the object to check

name - the exception message to use if the assertion fails

抛出:

ServiceException - if the object is null

notNull

public static void notNull(@Nullable
                           String string,
                           String name)

Assert that an object is not null.

AssetUtils.notNull(clazz, "name");

参数:

string - the string to check

name - the exception message to use if the assertion fails

抛出:

ServiceException - if the object is null

notZero

public static void notZero(Number number,
                           String name)

参数:

number -

name - name of number 'name must not be zero'

抛出:

ServiceException - if the number is null or 0

length

public static void length(String value,
                          String name,

                          int max)

Assert that value is in size [min~max] AssetUtils.length(obj,name,0,12)

• name out of size[0~12]
• name out of size[0~]
• name out of size[~12]

参数:

min - minimum size of value . -1 of skip validate

max - maximum size of value . -1 of skip validate

name - name of value

抛出:

ServiceException - if value size out of min ~ max.

range

public static void range(Number value,
                         String name,
                         int min,
