業(yè)務(wù)場(chǎng)景：在實(shí)際開發(fā)中，由于我們需要一些flowable的個(gè)性化查詢，而且他們提供的api無法滿足我的需求的時(shí)候，這個(gè)時(shí)候我們應(yīng)該考慮flowable有沒有那種自定義的sql方式，其實(shí)flowable已經(jīng)給我們預(yù)留了這樣的接口方便我們隨意擴(kuò)展。
這里我就講一種注解的方式擴(kuò)展自定義sql查詢

1、首先我們要定義一個(gè)mapper接口

public interface CustomCommentMapper {@Select({ "select t.* from act_hi_comment t where t.PROC_INST_ID_ = #{procInstId}" })List<Map<String, Object>> selectCommentsByProcInstId(String procInstId); }

2、配置mapper到config里面

//自定義sqlSet<Class<?>> customMybatisMappers = new HashSet<>();customMybatisMappers.add(CustomCommentMapper.class);configure.setCustomMybatisMappers(customMybatisMappers);

3、定義service

@Service public class CustomCommentService {@Autowiredprivate ManagementService managementService;public List<Map<String, Object>> getCommentsByProcInstId(String procInstId) {CustomSqlExecution<CustomCommentMapper, List<Map<String, Object>>> customSqlExecution = new AbstractCustomSqlExecution<CustomCommentMapper, List<Map<String, Object>>>(CustomCommentMapper.class) {@Overridepublic List<Map<String, Object>> execute(CustomCommentMapper customMapper) {return customMapper.selectCommentsByProcInstId(procInstId);}};return managementService.executeCustomSql(customSqlExecution);} }

4、測(cè)試

@Testpublic void testXml() {List<Map<String, Object>> comments = customCommentService.getCommentsByProcInstId("aa798e711a9a11eaa07cdc8b287b3603");System.out.println(comments);}
