In order to learn Spring Framework, I introduced STS, but since half-width space is u and it is very difficult to see, I will write down the procedure of change as a memo. The procedure is basically the same as for Eclipse.
Spring Tool Suite 4 Version: 4.6.0.RELEASE
STS installation path (depending on the person, but for reference)
$3 = $3.equals("·" )? "ᴜ" // Half-width blank Example: ▫ᵁᐡᶸᓑᴜՍ <!-- ↓ ↓ Change to the following ↓ ↓ --> $3 = $3.equals("" )? "ᴜ" // Half-width blank Example: ▫ᵁᐡᶸᓑᴜ Ս
that’s all. Have a good coding life. Thank you for your hard work.
