這期內(nèi)容當(dāng)中小編將會(huì)給大家?guī)?lái)有關(guān)怎么在SpringBoot中利用MybatisSQL對(duì)@Intercepts進(jìn)行過(guò)濾,文章內(nèi)容豐富且以專(zhuān)業(yè)的角度為大家分析和敘述,閱讀完這篇文章希望大家可以有所收獲。
開(kāi)發(fā)環(huán)境:
spring boot + mybatis
@Component @Intercepts({ @Signature(type = Executor.class, method = "query", args = {MappedStatement.class, Object.class, RowBounds.class, ResultHandler.class }) }) public class SqlInterceptor implements Interceptor { private Logger logger = LoggerFactory.getLogger(SqlInterceptor.class); @Override public Object intercept(Invocation invocation) throws Throwable { logger.info("Interceptor......"); // 獲取sql MappedStatement mappedStatement = (MappedStatement) invocation.getArgs()[0]; Object parameter = invocation.getArgs()[1]; BoundSql boundSql = mappedStatement.getBoundSql(parameter); String oldsql = boundSql.getSql(); logger.info("old:"+oldsql); // 判斷sql是否有where條件。改變sql。 boolean status = oldsql.toLowerCase().contains("where"); if (status) { BoundSql newBoundSql = new BoundSql(mappedStatement.getConfiguration(), oldsql + " and 1=1", boundSql.getParameterMappings(), boundSql.getParameterObject()); MappedStatement newMs = copyFromMappedStatement(mappedStatement, new BoundSqlSqlSource(newBoundSql)); invocation.getArgs()[0] = newMs; } // 繼續(xù)執(zhí)行 Object result = invocation.proceed(); return result; } @Override public Object plugin(Object target) { return Plugin.wrap(target, this); } @Override public void setProperties(Properties properties) { } // 復(fù)制原始MappedStatement private MappedStatement copyFromMappedStatement(MappedStatement ms, SqlSource newSqlSource) { MappedStatement.Builder builder = new MappedStatement.Builder(ms.getConfiguration(), ms.getId(), newSqlSource, ms.getSqlCommandType()); builder.resource(ms.getResource()); builder.fetchSize(ms.getFetchSize()); builder.statementType(ms.getStatementType()); builder.keyGenerator(ms.getKeyGenerator()); if (ms.getKeyProperties() != null) { for (String keyProperty : ms.getKeyProperties()) { builder.keyProperty(keyProperty); } } builder.timeout(ms.getTimeout()); builder.parameterMap(ms.getParameterMap()); builder.resultMaps(ms.getResultMaps()); builder.cache(ms.getCache()); builder.useCache(ms.isUseCache()); return builder.build(); } public static class BoundSqlSqlSource implements SqlSource { BoundSql boundSql; public BoundSqlSqlSource(BoundSql boundSql) { this.boundSql = boundSql; } public BoundSql getBoundSql(Object parameterObject) { return boundSql; } } }
上述就是小編為大家分享的怎么在SpringBoot中利用MybatisSQL對(duì)@Intercepts進(jìn)行過(guò)濾了,如果剛好有類(lèi)似的疑惑,不妨參照上述分析進(jìn)行理解。如果想知道更多相關(guān)知識(shí),歡迎關(guān)注億速云行業(yè)資訊頻道。
