Build (); SimpleModule simpleModule = new SimpleModule (); / / convert all Long types directly to String simpleModule.addSerializer (Long.class, ToStringSerializer.instance); simpleModule.addSerializer (Long.TYPE, ToStringSerializer.instance) ObjectMapper.registerModule (simpleModule); return objectMapper;} / * * logical deletion * @ return * / @ Bean public ISqlInjector sqlInjector () {return new DefaultSqlInjector ();}} the above is how to solve the problem of invalid mybatis-plus logic deletion.
