## 演示like,batchUpdate,in 操作 ```java public class S4Other { SQLManager sqlManager; UserMapper mapper = null; public S4Other(SQLManager sqlManager) { this.sqlManager = sqlManager; mapper = sqlManager.getMapper(UserMapper.class); } public static void main(String[] args) throws Exception { SQLManager sqlManager = SampleHelper.getSqlManager(); S4Other others = new S4Other(sqlManager); others.like(); others.in(); others.batch(); others.sqlResult(); } /** * like */ public void like() { String sql = "select * from user where name like #{name}"; Map paras = new HashMap(); String name = "%li%"; paras.put("name", name); List<UserEntity> users = sqlManager.execute(sql, UserEntity.class, paras); //同样效果 sql = "select * from user where name like #{'%'+name+'%'}"; paras = new HashMap(); name = "li"; paras.put("name", name); users = sqlManager.execute(sql, UserEntity.class, paras); //同样效果 SQLReady sqlReady = new SQLReady("select * from user where name like ?" ,new Object[]{"%"+name+"%"}); users = sqlManager.execute(sqlReady,UserEntity.class); } /** * in */ public void in() { //使用beetlsql提供的join函数,接受一个list变量 String sql = "select * from user where id in ( #{join(ids)} )"; List list = Arrays.asList(1,2,3,4,5); Map paras = new HashMap(); paras.put("ids", list); List<UserEntity> users = sqlManager.execute(sql, UserEntity.class, paras); } /** * batch */ public void batch() { //批量插入 UserEntity user1 = new UserEntity(); user1.setName("b1"); user1.setDepartmentId(1); UserEntity user2 = new UserEntity(); user2.setName("b2"); user2.setDepartmentId(1); //根据组件批量更新 List<UserEntity> data = Arrays.asList(user1,user2); sqlManager.insertBatch(UserEntity.class,data); data.get(1).setName("bb11"); sqlManager.updateByIdBatch(data); //循环删除,执行多次 data.stream().forEach(userEntity -> mapper.deleteById(userEntity.getId())); } /** * 不执行,只得到sql语句和参数 */ public void sqlResult(){ Map map = new HashMap(); map.put("name","li"); SQLResult sqlResult = sqlManager.getSQLResult(SqlId.of("user","select"),map); String targetJdbc = sqlResult.jdbcSql; Object[] paras = sqlResult.toObjectArray(); System.out.println(targetJdbc); System.out.println(Arrays.asList(paras)); } } ```
