Provided is a service-orientated software construction method. The method comprises the steps that firstly, an SOA foundation platform is constructed to be used as the foundation environment for constructing service-orientated software; secondly, a service model is analyzed and services are abstracted, wherein the process is supported through a service management platform; thirdly, the services are developed and combined, wherein the process is achieved through an integrated development environment of the services, supporting from universal components, such as a front part showing component, database access, a log service component and a messaging component is provided for the developing process of novel services, and supporting from various integrated components such as technical protocol HTTP, Web Service, Socket, JMS are provided for the developing of integrated services; at last, the services are operated and monitored. When the technical scheme is executed, the problems that fusion type application software is fast in service requirement change, low in software reuse agree, mixed in technology and service and the like can be solved, the development efficiency and the delivery quality are effectively improved, and meanwhile operation and maintenance cost is greatly lowered.
