ParamsRequestCondition
public ParamsRequestCondition(String... params)
Create a new instance from the given param expressions.- 参数:
params
- expressions with syntax defined inRequestMapping.params()
; if 0, the condition will match to every request.
方法详细资料
getExpressions
public Set<NameValueExpression<String>> getExpressions()
Return the contained request parameter expressions.
getContent
protected Collection<org.springframework.web.servlet.mvc.condition.ParamsRequestCondition.ParamExpression> getContent()
从类复制的说明:AbstractRequestCondition
Return the discrete items a request condition is composed of.For example URL patterns, HTTP request methods, param expressions, etc.
- 指定者:
getContent
在类中AbstractRequestCondition<ParamsRequestCondition>
- 返回:
- a collection of objects (never
null
)
getToStringInfix
protected String getToStringInfix()
从类复制的说明:AbstractRequestCondition
The notation to use when printing discrete items of content.For example
" || "
for URL patterns or" && "
for param expressions.
combine
public ParamsRequestCondition combine(ParamsRequestCondition other)
Returns a new instance with the union of the param expressions from "this" and the "other" instance.- 参数:
other
- the condition to combine with.- 返回:
- a request condition instance that is the result of combining the two condition instances.
getMatchingCondition
@Nullable public ParamsRequestCondition getMatchingCondition(HttpServletRequest request)
Returns "this" instance if the request matches all param expressions; ornull
otherwise.- 返回:
- a condition instance in case of a match or
null
otherwise.
compareTo
public int compareTo(ParamsRequestCondition other, HttpServletRequest request)
Compare to another condition based on parameter expressions. A condition is considered to be a more specific match, if it has:- A greater number of expressions.
- A greater number of non-negated expressions with a concrete value.
It is assumed that both instances have been obtained via
getMatchingCondition(HttpServletRequest)
and each instance contains the matching parameter expressions only or is otherwise empty.
