It is found that in the cases of uniform dot levels and dot-superconductor couplings, the Josephson phase transition will be suppressed. This is manifested as the fact that with the enhancement of the electron correlation, the supercurrent only arrives at its $\\pi'$ phase but cannot enter its $\\pi$ phase. Moreover, when the dot levels are detuned, one $\\pi'$-phase island appears in the phase diagram.
