@Intercepts({
@Signature(type=Executor.class,method="update",args={http://MappedStatement.class,Object.class}),
@Signature(type=Executor.class,method="query",args={MappedStatement.class,Object.class,RowBounds.class,ResultHandler.class})
})
public class EncryptInterceptor implements Interceptor {
public static final Logger logger = LoggerFactory.getLogger(EncryptInterceptor.class);
@Override
publihttp://c Object intercept(Invocation invocation) throws Throwable {
dealParameter(invocation);
Object returnValue = invocation.proceed();
dealReturnValue(returnValue);
return returnValue;
}
//查询参数加密处理
private void dealParameter(Invocation invocation) {
MappedStatement statement = (MappedStatement) invocation.getArgs()[0];
String mapperl = ConfigUtils.get("mybaits.mapper.path");
String methodName = statement.getId().substring(statement.getId().indexOf(mapperl) + mapperl.length() + 1);
if (methodName.startsWith("UserBaseMapper")){
if(methodName.equals("UserBaseMapper.updateDriver")){
((Driver) invocation.getArgs()[1]).encrypt();
}
}
logger.info("Mybatis Encrypt parameters Interceptor, method: {}, args: {}", methodName, invocation.getArgs()[1]);
}
//查询结果解密处理
private void dealReturnValue(Object returnValue){
if(returnValue instanceof ArrayList>){
List> list = (ArrayList>)returnValue;
for(Object val: list){
if(val instanceof Passenger){///
//TODO
}
logger.info("Mybatis Decrypt result Interceptor, result object: {}", ToStringBuilder.reflectionToString(val));
}
}
}
@Override
public Object plugin(Object target) {
return Plugin.wrap(target, this);
}
@Override
public void setProperties(Properties properties) {
}
}
