Description

Jar packet format localization method

Technical Field

The invention relates to the technical field of computers, in particular to a jar packet format localization method.

Background

Java is an object-oriented language, and its programs have strong cross-platform capabilities. Generally, Java programs are packaged into jar or war packages and then used. At the PC side, Java programs are usually packaged into jar packages, however, the current method for opening jar packages at the PC side is relatively complex. Currently, the running mode of Windows can open jar packages by using the following methods: 1. opening a command line, and running java-jar xxx, jar (xxx is the package name of jar); 2. modifying the opening mode of a jar file, then finding 'HKEY _ CLASSES _ ROOT \ Applications \ java.exe \ shell \ open \ command' in a registry, adding a parameter '-jar' (no quotation mark) into a file opening command, wherein the modified numerical values are similar: "C: \ Program Files \ Java \ jre7\ bin \ javaw. exe-jar"% 1 ".

Disclosure of Invention

The invention aims to overcome one or more defects in the prior art and provides a jar packet format localization method.

The purpose of the invention is realized by the following technical scheme: a jar packet format localization method is characterized by comprising the following steps:

creating a localization program header, wherein the localization program header is used for guiding the jar packet to start;

and enclosing the localization program header and the jar into a file.

Preferably, creating a localization program header comprises:

analyzing a parameter list of a main function of the localization program header, wherein a first parameter in the parameter list is a program name of the localization program header, and all parameters except the first parameter in the parameter list are operation parameters of jar packets;

creating a running process of a jar packet by using an API (application programming interface) for creating the process in an operating system;

and transmitting a command line character string of a start jar packet for the corresponding parameter in the running process.

Preferably, the API for creating the process in the Windows system is CreateProcesses.

Preferably, the command line character string is java-jar name argv.

Preferably, the enclosing the localization program header and jar into one file comprises:

creating a new file;

writing all the localized program headers into the new file;

and completely writing the jar packet into the new file, wherein the start position of the jar packet in the new file is the end position of the localized program header in the new file.

The invention has the beneficial effects that: the invention provides a jar packet format localization method, after localization processing, jar packets can be directly opened by double-click at a PC (personal computer) end instead of using a command line or modifying a registry, and user experience is greatly improved.

Detailed Description

The technical solutions of the present invention will be described clearly and completely with reference to the following embodiments, and it should be understood that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without inventive effort based on the embodiments of the present invention, are within the scope of the present invention.

Referring to fig. 1 to fig. 3, the embodiment provides a jar packet format localization method:

as shown in fig. 1, a jar packet format localization method includes:

s1, creating a localization program header, wherein the localization program header is used for guiding the jar packet to be started.

The localization program header is a program that can run directly on the operating system, such as an exe format program on a Windows system.

In some embodiments, as shown in FIG. 2, creating a localization program header includes:

s11, analyzing a parameter list of the main function of the localization program header, wherein a first parameter in the parameter list is a program name of the localization program header, and all the other parameters except the first parameter in the parameter list are operating parameters of jar packets.

And S12, creating the running process of the jar packet by using the API of the creating process in the operating system.

The API for creating a process in different operating systems is different, for example, the API for creating a process in a Windows system is CreateProcess, and the function of the API is defined as follows:

BOOL CreateProcess(

LPCTEST lpApplicationName,// application name

LPTSTR lpCommmandedline,// command line string

LPSECURITY _ ATTRIBUTES lpProcessAttributes,// Security Attribute of Process

LPSECURITY _ ATTRIBUTES lpTHREADATTRIBUTES,// thread's security ATTRIBUTES

BOOL bInheritHandles,// whether or not to inherit the parent process's attributes

DWORD dwCreationFlags,// CreationFlags flag

LPVOID lpENEnvironment,// pointer to new context Block

LPCTESTR lpCcurrentDirectory,// a pointer to the current directory name

LPSTARTUPINFO lpStartupInfo,// information passed to the new process

LPPROCESSS _ INFORMATION lpProcessinformation// INFORMATION returned by new process

);

And S13, transmitting a command line character string of a starting jar packet for the corresponding parameter in the running process.

Specifically, the command line character string is java-jar name argv.

And S2, combining the localization program header and the jar into a file.

In some embodiments, as shown in FIG. 3, enclosing the localization program header and jar into one file includes:

s21, creating a new file.

And S22, writing all the localized program headers into the new file.

S23, all the jar packets are written into the new file, and the starting position of the jar packets in the new file is the ending position of the localized program header in the new file.

Namely, reading the jar packet, and starting the writing of the jar packet at the position where the localization program head ends in the new file until the jar packet is completely written into the new file.

The foregoing is illustrative of the preferred embodiments of this invention, and it is to be understood that the invention is not limited to the precise form disclosed herein and that various other combinations, modifications, and environments may be resorted to, falling within the scope of the concept as disclosed herein, either as described above or as apparent to those skilled in the relevant art. And that modifications and variations may be effected by those skilled in the art without departing from the spirit and scope of the invention as defined by the appended claims.
