Java EE Gateway Website Performance Optimization Technique Research And Implementation

As the security and the shared jolt of government and enterprise, the authority system has become the important part of the information construction, also including coarse-grained authority control and fine-grained authority control. The paper accomplishes the connection of coarse-grained and fine-grained authority control by quoting the Serlvet specification of filters, Struts2validators, Strtus2interceptors and other components.For the problems of the user’s unified logging, it puts forward to the coarse-grained authority control based on the Serlvet specification of filters, which solves the protected resources while visiting websites, for it must visit websites after logging into systems. For the issues of the data visisting between the upper and lower levels or the same levels, it brings about the coarse-grained authority control based on Struts2validators, which makes full use of the manual validate() method of interceptors in order to complish the data visiting of different levels.For the problems of the system modeling, it puts forward to the modeling method of the entity domain and adopts reflectional modelings, such as many-to-many and many-to-one entity relationships, which makes the database design become more consistent with the object-oriented design and analysis, making the system easier to achieve. For the problems of each operation corresponds to an authority, it brings about the fine-grained authority control based on Strtus2interceptors, defining the authority notes and marking in the appropriate method of the Action in order to achieve the authority interceptor. Achieving the dynamic management and allotment of the authority groups can guarantee the flexibility of the system.The authority system brought about by the paper has been realized in the system of a provincial office.The convenience of the authority management can improve the security and sharing of the system.
