java - How do you redirect to another URI and access an object from the previous modelAndView -



java - How do you redirect to another URI and access an object from the previous modelAndView -

i have next code. want access booleanvalueobj on nextpage.jsp. how done? object not available nextpage() method on every request, requestparam seems it's not appropriate.

@requestmapping(method=requestmethod.post) public modelandview sendemail() { modelandview modelandview = new modelandview(); modelandview.addobject(booleanvalueobj, true); modelandview.setviewname("redirect: /nextpageclass"); homecoming modelandview; } @requestmapping("/nextpageclass") public class nextpagecontroller { @requestmapping(method = requestmethod.get) public modelandview nextpage() { modelandview modelandview = new modelandview("/nextpage"); homecoming modelandview; } }

you can't pass booleanvalueobj redirected page. if booleanvalueobj boolean value, seems appropriate passed /nextpageclass thru request parameters.

@requestmapping(method=requestmethod.post) public modelandview sendemail(httpservletresponse resp) { resp.sendredirect("/nextpageclass?booleanvalueobj=true"); homecoming null; } @requestmapping("/nextpageclass") public class nextpagecontroller { @requestmapping(method = requestmethod.get) public modelandview nextpage(httpservletrequest req) { modelandview modelandview = new modelandview("/nextpage"); boolean booleanvalueobj = null; string booleanvalueparam = req.getparameter("booleanvalueobj"); if (booleanvalueparam != null) booleanvalueobj = boolean.parse(booleanvalueparse); modelandview.addobject("booleanvalueobj", booleanvalueobj); homecoming modelandview; } }

java spring

string - what is the difference between "some" == "some\0" and strcmp("some","some\0") in c++? -

string - what is the difference between "some" == "some\0" and strcmp("some","some\0") in c++? - what difference between "some" == "some\0" , strcmp("some","some\0") in c++? why if("some" == "some\0") returns false , if(!strcmp("some","some\0")) returns true ? see next diagram. shows 2 strings in memory, content in box, beside box you'll see address of each one. when you're doing if("some" == "some\0") comparing addresses. translated if (0xdeadbeef == 0x0badcafe) false. when utilize strcmp , compare content of each box until reach \0 in each of them. that's why sec test returns true. if alter first test if("some" == "some") compiler may potentially see same strings , store them once. means test transform if (0x0badcafe == 0x0badcafe) true. c++ string comparison
