The embodiment of the present invention provides a kind of store method and device of page frame stream conversation information.Can make page frame stream conversation information be kept in the page of client, thereby reduce the memory cost of server, guarantee the stable operation of server; When server failure, can on other server, rebuild session information, thereby guarantee greatly the reliability service of application program simultaneously.
Embodiment 1: the embodiment of the present invention 1 provides a kind of store method of page frame stream conversation information, is illustrated in figure 1 the schematic flow sheet of 1 supplying method of the present embodiment, and described method comprises:
Step 11: when client operates the processing page of business, the page frame stream conversation information sequence that server end is created turns to character string.
In this step 11, when client operates the processing page of business, when namely user clicks menu or newly initiate a business operation in system, client and server end can carry out corresponding mutual, and the business application in this server end will create corresponding page frame stream conversation information.In specific implementation process, the form that this page frame stream conversation information can page frame stream conversation object is preserved.
After server end has created corresponding page frame stream conversation information, just can, when the page echo of client, this page frame stream conversation information sequence be turned to corresponding character string.In specific implementation process, page frame stream conversation information sequence is turned to character string and can have multiple implementation, for example this page frame stream conversation information can be encoded to the form based on key-value pair, and the stack of object data form, make this page frame stream conversation information sequence turn to character string.
For instance, a for example simple java object (java bean) structure, be in fact and following programming statement: Map<String, Object> is consistent, the attribute-name of bean be just mapped as Map's " key ", and the property value of bean be just mapped as Map's " value ", for more complicated object model, this structure is nested often.
In addition, be generally used in the business object of preservation state and page frame stream conversation information and also often with Container Type or array type, characterize, therefore, as long as realize the mapping of above structure and character string, be that object tree is mapped as Map form, nested object map is nested Map form, and various Container Types are mapped as array, can be mapped as character string so for the business object for preservation state and page frame stream conversation information under normal circumstances.
The serializing form of fundamental type for definition as shown in table 1 below, in actual applications, the mode shown in can according to the form below 1 is shone upon or changes:
| Type | Serializing form | Explanation |
| String | The character string of String to representative | |
| Integer/lint-long integer | The character string that 16 systems represent | Adopt 16 systems to represent both can reduce the size after serializing, serializing efficiently and unserializing |
| Other value type | The character string that 16 systems represent | |
| Date | The character string that 16 systems represent | Date and long equivalence |
| Boolean type | T/F |
Table 1
For complex object, except the mode of upper table 1, also need to utilize following basic separator to complete the process of serializing, shown in table 2 specific as follows:
| Separator | Title | Usage |
| ， | Word separator | Separate different words, for example different attribute-name, different value |
| ； | Line Separator | For array type, separate different objects, form object array |
| {} | Level separator | For multiplet, { } represents one deck wherein, its object |
| data structure also can be described in the same way | ||
| $ | object structure-value separator | in the situation that object structure can produce ambiguity, increase this descriptor and carry out disambiguation |
| % | escape character | according to certain escape rule, change. |
Table 2
With concrete serializing example, describe the object structure (by the composite object structure of pseudo-representation) being first defined as follows below:
class?obj1
{
String?a；
Date?d；
}
class?obj2
{
String?b；
obj1[]c；
}
class?obj3
{
String?f；
obj2?o；
}
Then the structure based on above, carries out assignment to it, shows business object as follows:
F=test1//here " test1 " is defined as arbitrary character string, as follows with
O is object obj2, and it is defined as follows:
o.b＝test2；
The length of o.c is 2, wherein c[0] and c[1] be defined as follows respectively:
c[0].a＝utest1
C[0] .d=2009-4-28 (being defined as the date, lower same)
c[1].a＝utest2
c[1].d＝2009-4-29
After above-mentioned assignment, as shown in Figure 2, in Fig. 2: obj3, obj2 and obj1 are nest relations, its level of nesting is more inward just darker for the nested structure of indicated business object in this example; Leaf node on test1, test2, utest1, utest2,2009-4-28 and 2009-4-29 position representative object tree, this business object structure can be used object diagram navigation language OGNL (Object-Graph NavigationLanguage) expression formula to be expressed as follows:
f＝test1
o.b＝test2
o.c[0].a＝utest1
o.c[0].d＝2009-4-28
o.c[1].a＝utest2
o.c[1].d＝2009-4-29
Then on the basis of above-mentioned expression formula, by the serializing mode described in the present embodiment 1, above-mentioned business object is carried out to serializing, finally forms following form:
f{test1}，o{b{test2}，c{{a{utest1}，d{2009-4-28}}；{a{utest2}，d{2009-4-29}}}}}
By above-mentioned mode, just can complete the serializing process of page frame stream conversation information, and then proceed follow-up operation.
