mybatis plus实现多租户方案

注意：方案的数据库mapper层采用的是tk.mybatis

多租户插件类 MultiTenantPlugin

public class MultiTenantPlugin implements Interceptor{

    private static PaginationInterceptor paginationInterceptor = new PaginationInterceptor();

    private static Set<String> multiTenantTable = new HashSet<>();

    @Value("${multi.tenant.table:}")
    private String multiTenantTables;

    @Value("${multi.tenant.enable:}")
    private boolean multiTenantEnable;

    @PostConstruct
    public void afterPropertiesSet() {
        if (multiTenantEnable) {
            initMultiTenantTable();
            initTenantSqlParser();
        }
    }
