Type conversion when mybatis uses generator to automatically generate code

Use the generator of mybatis to automatically generate code, but in the Oracle database, number (6, 2) is always automatically converted to bigdecimal, and I want to convert it to float type

In this way, a type converter needs to inherit the javatyperesolver interface.

Add the type conversion configuration location in the mybaties configuration file generatorconfig. xml.

<Javatyperesolver type = "com. generator. myjavatyperesolver"> <property name = "forcebigdecimals" value = "false"/> <! -- Type parser --> </javatyperesolver>

Main Code of type converter myjavatyperesolver

Public fullyqualifiedjavatype calculatejavatype (introspectedcolumn) {// todo auto-generated method stub fullyqualifiedjavatype answer; jdbctypeinformation = typemap. get (introspectedcolumn. getjdbctype (); If (jdbctypeinformation = NULL) {Switch (introspectedcolumn. getjdbctype () {case types. decimal: Case types. numeric: If (introspectedcolumn. getscale ()> 0) {// convert to float answer = new fullyqualifiedjavatype (float. class. getname ();} else {If (introspectedcolumn. getlength ()> 18 | forcebigdecimals) {answer = new fullyqualifiedjavatype (bigdecimal. class. getname ();} else if (introspectedcolumn. getlength ()> 9) {answer = new fullyqualifiedjavatype (Long. class. getname ();} else if (introspectedcolumn. getlength ()> 4) {answer = new fullyqualifiedjavatype (integer. class. getname ();} else {answer = new fullyqualifiedjavatype (short. class. getname () ;}} break; default: Answer = NULL; break ;}} else {answer = jdbctypeinformation. getfullyqualifiedjavatype ();} return answer ;}
