Apache Celix 是一个使用 C 和 C++ 实现的 OSGi 规范的项目。提供了使用组件和面向服务编程来开发模块化应用的框架。
一个 C 版本的激活器示例：
//${WS}/myproject/bundles/hello_world/private/src/hello_world_activator.c
#include <stdlib.h>
#include <stdio.h>
#include "dm_activator.h"
struct userData {
char * word;
};
celix_status_t dm_create(bundle_context_pt context, void **out) {
celix_status_t status = CELIX_SUCCESS;
struct userData* result = calloc(1, sizeof(*result));
if (result != NULL) {
result->word = "C World";
*out = result;
} else {
status = CELIX_START_ERROR;
}
return status;
}
celix_status_t dm_init(void* userData, bundle_context_pt context, dm_dependency_manager_pt manager) {
struct userData* data = (struct userData *) userData;
printf("Hello %s\n", data->word);
return CELIX_SUCCESS;
}
celix_status_t dm_destroy(void* userData, bundle_context_pt context, dm_dependency_manager_pt manager) {
free(userData);
return CELIX_SUCCESS;
}
